Description
This is my bid to create the last shirt pattern you'll even need. At its heart, this is a close-fitting button-up shirt for men. It comes with options (and option packs) that let you make this into whatever shirt you want it to be.
Very doable
Shirts take a bit of practice, and include some precise sewing, but in general aren't really that hard to make.
Pattern options
The pattern comes with a fit option pack, a style otions pack, and a whopping 38 options that allow you to tweak every aspect of your shirt. Make sure to read about the options before you start.
Designed by yours truly
This pattern is my own design, but I want to give credit to the drafting method of Gareth Kershaw, as the basic block I started from is an adaptation of his.
