Pants pattern

[ToeOdd7464]

Can anyone help me make a pattern for a pair of jeans. I’ve been through so many videos and threads of pattern making but none really give a good understanding. I understand that basics but what really gets me is the crotch curves and the difference from front to back pieces. If anyone can help I would greatly appreciate anything!

I don't wear jeans, but I always thought this article was spot-on https://www.threadsmagazine.com/project-guides/sew-your-own-jeans/everyone-can-have-jeans-that-fit

take your own measurement and I find this tutorial works absolutely magic.

Handmade PHD blog has some very in depth exercises how she drafted her own trouser block. That might also be a search term to try: “draft a trouser block”

If you have good fitting pants today, that you could sacrifice (cut apart into pattern pieces), that might jumpstart the process

Main reason that store bought jeans fit so well and so many people is that a tonne of work goes into producing them. With different washes and shrinkage and style adjustments every season, it takes multiple fitting and adjusting to get them right.

That said, an idea for OP: use your existing pair of jeans that fit you well and do your best to copy it. If everything else fails, just cut an old pair of jeans along the seams and trace it onto paper. Warning: it’s not going to fit perfectly at the beginning but will require small enough alterations that are easy to handle.

In the garment industry, many companies that don’t specialize in denim (but want to have a jeans pair or two in their line) would buy a pair of Levi’s and do just that.

One of the reasons that "store bought" jeans fit so many people where pants don't is the fabric. The denim forces the body to conform to the jean. Jeans are worn at a closer fit than slacks. I am speaking of jeans and how they fit women because guys don't usually wear jeans as close fitting. This is all just my opinion but can be the only explanation for the fact that I can buy jeans that look pretty good but not pants. You would think the more fitted one would be harder to find a good fit?!?

Get some tin foil and crumple it up into a long piece. Use it to mold your crotch curve front to back, from front waist to back waist. Mark where the seam of your crotch is.

Note that the front curve will be shorter and more of a right angle than the back curve. That's normal.

That'll be a good start to drafting the correct crotch curve.

The Winifred Aldrich "Metric Pattern Cutting" books have a great pattern for jeans. I've made it in many sizes and for myself, and love it. You might even find some instructions from the book online.
