McCall's M7938 / M7989 - Yaya Han Coat, View A

If you follow me on Instagram, then you will have been spammed by loads progress photos
of this coat.  It was an epic make, I have a lot to say about it and there are loads of photos.


The pattern is McCall's M7938, which is a Yaya Han costume pattern, but I laugh in the face of costume and will be wearing this all winter!  Also, I have to thank Sian from Kittenish Behaviour for tipping me off about this pattern.

There are two views, and the photo below is View B from the pattern envelope.  This is on M7938, which is sizes 6 - 22.

This photo is View A, and this from McCall's M7989 which is sizes 18W - 32W.

Here are the line drawings from both patterns.

Fabric and Interfacing

Before I get into the gory details, here are the fabrics and interfacings I used.  The main fabric is 100% wool from My Fabrics.  It's called Fulled Loden, and the colour is auburgine.   The lining is also from My Fabrics, and is called Diamonds Jacquard Lining Fabric.

The interfacing is all from Tailor Mouse.  I used Medium Weight Woven Canvas Fusible for the coat fronts, under collar and hems.  I used Lightweight Woven Fusible Cotton for the front and back facings, upper collar, pocket flaps and martingale.  The buttons are from Totally Buttons.

I bought all of these (and the pattern) myself, and just wanted to link them in case anybody is interested.


As it is me, obviously there are some modifications...  

Firstly, I shortened the body by 4.5 cm.  To work this out, I already knew the length of the back neck to waist on the other coats I've made, so shortened the back to that length.  Then I shortened the other bodice pieces to match.  I also lengthened the skirt by 1 inch.

The collar stand extends past the end of the collar on one side, and you can see this in the line drawing above.  I made it on my toile, but didn't think it really worked with the lapels on View A, so I didn't put it on my coat.  I also didn't do the cuffs on View A as I didn't love them on my toile.

On the line drawing you can also see that the shoulder seam is dropped down onto the bodice back.  I didn't love this either, as I thought it would make it difficult to stablise the shoulder seam, so I moved it up to the shoulder.

The biggest modification I made was to the the skirt.  There isn't a side seam on the skirt, instead it attaches to the skirt back piece, then goes right around as one piece and joins the coat front.  Below is the coat front, skirt and skirt back as on the pattern.

As you can see, this isn't far off a full circle skirt.  I made it as is on my toile, and as much as I absolutely loved it, I didn't think it was for me.  I'm pretty small, and felt that it would swamp me a bit.  Also, I thought that it would be quite heavy in the wool fabric.  

So I drafted a quarter circle skirt, and you can see this with the coat front and skirt back below.  This is what I've used on my coat.

I cut out one quarter circle skirt and sewed it to my toile, and here are a few photos below.

The original skirt pattern is on the side without a sleeve, and you can see how fabulous it is!  It looks amazing in the lighter weight fabrics used on the pattern envelope photos.  My quarter circle skirt is on the side with the sleeve.

Skirt as on the pattern above, and quarter circle skirt below.

I also made a lot of alterations to the insides.


As on some of my other coates, I drafted the interfacing pieces using some of the classes on Bluprint - I've bought these classes myself, and am mentioning them in case they are helpful.  

I drafted back, side back and side front stays from a class called "Classic Tailoring: The Blazer".  In the photo below, the pieces at the top are the back, side back and side front pieces; and the pieces at the bottom are the corresponding stay pieces.

And here are the stays attached to the bodice pieces, I used a medium weight cotton for this, and I have stablised the shoulder seams with twill tape.

I drafted the interfacing for the coat fronts from a class called "Essential Guide To Tailoring - Structure And Shape".  On the left in the below photo is the coat front.  On the right are the interfacing pieces for the front and lapel, and in the centre the pieces for the front shoulder.

Below is the interfacing pieces attached to the coat fronts.

 You can see the shoulder support attached, the taped roll line and taped edges.

Lining and Facings

The lining on the pattern is the same as the bodice pieces, so I re-drafted it using the brilliant tutorial on the Grainline Studios blog.  

The pattern doesn't have a face neck facing, and the front facing is the same as the coat front, which I thought might be a bit bulky in my heavy fabric.  Below left is the re-drafted front facing, centre is the coat front, upper left is the back neck facing and lower left is the coat back. 

 Below is the re-drafted lining pieces.

Here's the coat inside out, so you can see the lining and facings. 

And I've added a pleat to the centre back of the lining to give the lining a bit more movement when the coat is being put on/taken off.



There are three functioning buttonholes on this coat, and I made them as bound buttonholes.  


The buttonholes on the lapels are machined decorative buttonholes and I haven't cut them open, just sewed the buttons on.

Coat Skirt and Pockets

I felt that the skirt waist needed stablised to help support the weight of the fabric.  I found some Christian Dior ribbon when I was looking for something else, (I completely forgot I had it and think it was on some perfume I got last Christmas), and had to use it.  The bodice waist is stablised with seam binding.

The pockets are attached at the top of the big skirt pieces, and there is a pocket flap on the right side.  It wasn't the easiest thing to sew, but I got there in the end.  Here's what it looks like from the inside.


Here's the pocket flap once it's finished, I used the lining fabric on the underneath of the flap to reduce bulk.

Collar and Facing

Because I had added a back neck facing, I ended up doing my own thing with attaching the collar.   Here's what it looks like.  The "Me Made" label is from Kylie And The Machine, and the "Contains Cat Hair" label is from Pink Coat Club.

I forgot to take any photos of sewing the collar pieces together, but below is the under collar attached to the coat.

And below is the upper collar attached to the facing.

Again, I forgot to take any photos of attaching the coat and facings together, but here's what it looked like once it was done.

The front and back seams within the collar still needed attached, and I'm now hoping that all of this is going to make sense!   I wanted to attach together the two seams between the collar and stands, and also attach the seams between the facing and the coat back together.

This is the collar to stand seams being sewn together,

and this is the facing to coat back being sewn together.  I used a herringbone stitch for this, and I really hope that all makes sense!     



Next were the sleeves, and I used my tried and tested bias strip method.  Here is a great tutorial video from Gretchen Hirsch.  You cut a 2" wide strip of the main fabric on the bias, and cut it about 18" long.

Pin the centre to the top of the sleeve head, where the mark is to join the shoulder seam.

Sew it using a 1/2 inch seam allowance and 5.0 stitch length.  As you sew, you stretch out the bias strip - which is very hard to photograph with one hand!

And this magically gathers up the sleevehead as in the photo below!  It then gets pressed over the end of a sleeve board.

Pin and sew the sleeve in as normal, and it looks like the photo below.  I'm holding one long edge of the bias strip, the edge in the middle is the other long edge, and the wavy edge is the sleeve head.

Next, I pinned the two long edges of the bias strip together and hand sewed them to the sleeve head. 

This helps to pad out the top of the sleeve head, so it looks like this.  And after that I added the shoulder pads.

Also, I drafted a Martingale for the back, because it turns out I love the look of them.  I say drafted - it's a rectangle 2" deep, and the length of the back waist seam plus about 5 cm then add a seam allowance.  I interfaced it, and the back is the lining fabric.  

After that, everything is fairly straight-forward.  I hemmed the sleeves and coat, sewed together the lining, and attached it to the coat.  Then the lining got hemmed separately to the coat, and attached at the seam joins using thread chains.  I find this works better on a wide hem, rather than attaching it directly to the coat hem.

Phew!!  That is a lot of waffling, and if you made this far - well done!  Here are lots of photos of the finished coat.

I think it goes without saying that I love this coat, and thank you for reading!



  1. What a wonderful coat! Thank you for all the explanations and links.

  2. Beautiful. You look so stylish and you'll be warm as toast too! Thanks for all the photos and details which are fascinating. Just finished my second coat which is the Grainline Yates in a smoke blue wool from Activefabrics. I couldn't be more pleased with it. I've studied your coat posts avidly and have learned a lot from you so many thanks! Enjoy wearing your lovely coat!

    1. Thank you so much Elaine! My coat is really warm, and I've been very glad of it this week as the weather has been so cold. I just googled the Grainline Yates coat, and it's gorgeous. I love the lapel and the way the pockets are in the horizontal seam. Well done on making it, I bet it's fabulous, and happy wearing! Also, I hadn't heard of Active Fabrics, and have just had to google it too... :)

    2. The wool was their Hannah wool which is soft and warm. The pattern went together well and I didn't have to make too many adjustments. I just shortened the upper body an inch, took in the shoulders a little, added a layer of flannel interlining to just the body area, and added shoulder pads. Oh and poppers as I'm not confident about bound buttonholes. Yours are perfect and Im jealous!

    3. It's always great when you don't have to make many adjustments! I bet it toasty warm with the interlining. I like a bound buttonhole because I think I have more control in making it than a machined buttonhole. The method I use is to make little welts for the buttonhole frame, rather than using a patch of fabric. I've tried the patch, but found it hard to get the frame even looking.

    4. Thanks Lynne. I will definitely have another try at them.

  3. You should be incredibly proud of this coat because it's absolutely stunning! A work of art. Thanks for sharing all of your process. Fab stuff. xx

    1. Thanks Diane!! I really love it, and glad you like all the progress details. I always love seeing how someone has put a garment together.

  4. It's a really gorgeous coat Lynne, and it's interesting to see all the work that went into it. I'm always impressed by all of your modifications to make things just as you want them. I'm sure you'll get a lot of compliments whenever you wear this!

    1. Thanks Ruth! I always love reading posts about how other folks put their garments together, and I'm loving wearing my coat.

  5. I can't believe the amount of work that went into making this coat. It's fabulous. The buttons give it a military feel.

  6. Looks phenomenal Lynne. Amazing work. And the quarter circle skirt takes it from costume to couture 💗 Jay Jay xx
