This is gonna be short & sweet!
When I sewed up my first pair of Thurlows, the only complaint was that the back pockets weren’t deep enough to accomodate my phone or wallet. Which, I mean, back pockets pretty much ONLY exist for a phone or wallet as far as I’m concerned.
Can we all just step back for a second and have a moment of silence for this tragedy that is unfolding.
Measuring the pockets shows that they are only about 2.5″ deep. If this is all gravy in your world, do solider on with the unaltered pattern. If not, I hope you saved a bit of tissue because we have pattern pieces to slash and tape!
Here is my modified pattern piece. What you want to do is add length both above and below the fold line, to ensure that the pocket still folds up properly once we stick in the pants (hurr durrr). This is pretty easy – just slash a straight line above the fold line, tape in a gob of tissue paper (or you can use regular paper, IDGAF. I use tissue since I have tons on hand & it makes everything easy to fold back up!) and then repeat below the aforementioned fold line. To fit my iPhone, I added 2.5″ to each slash.
When you’re done hacking, fold the tissue on the fold line (notice that the bottom matches up to the top notch – not the top of the tissue). This is how deep your pocket will be. My phone fits, yay!
And here is an action shot, courtesy of my second pair of Thurlows.
If your muslins are ready, go ahead and cut your fabric – you did prewash… right?! 😉 If you are planning on making your trousers in a plaid or striped fabric and fancy a bit of bias-cut on the welts & waistband (because YAY for not having to match those parts!), Liz has a great tutorial on altering pattern pieces for a bias grainline. For the actual matching at the side seams and everywhere else, Check out Tasia’s tutorial for matching plaids. If you are smart & opted for a solid, non-directional fabric – lucky you! You can just follow the cutting layout included in the pattern 🙂
We will start sewing on Monday!

Thanks for the great idea. Why are all pockets so shallow in pants these days? They look terrible and won’t hold anything.
I’ve started engineering horizontal iphone depth into my front pockets… It’s really handy.
Great tutorial, I think I will do that to my pants
I was reading this post last night before bed and this morning it was still up on my desktop so I refreshed to see if you had posted anything new. I think I am a little too obsessed with your blog lol. I also REALLY wish I was a part of this sew a long 😦
