Spent the last few days sewing up some caps and searching the internet for some good patterns and instructions. For a good basic pattern check out: Combat Cap . It doesn't get any easier than this pattern.
It's what you do to the basic pattern that will make it yours. In my case doubled the height to give it a floppy effect that can be worn several ways. I also detailed the visor.
Caps makes great use of leftover fabric.
This next one is from this tutorial-the Eddie Cap. It's more of a stream train driver look.
Both are very easy and will take less than an hour each.
These are all made with (leftover) wool suiting with satin pin-stripe lining.
Easy, scrap fabric and made in less than an hour. What more could you want?
