Granted the flag in the picture needs a bit more blocking, but you get the idea. I used Rich Red and Winter White in the Classic Wool for this pattern, and in small quantities. Chart can be followed to crochet as well, using a 5.5mm crochet hook, and single crochet throughout.

This is an ideal project to use up wool scraps - or if you’re itching to use a full skein of each red and white, you’ll have a lot of patches made to distribute to friends! (And enough to make laundry-machine felting worthwhile, instead of doing it for just one patch!)
