They hold up quite well. The nasum-patch has been washed several times. They tend to crack a bit if you use stretchy fabric like a t-shirt, though. Also, if you do a t-shirt, you don't want the paint to soak into the fabric, at least if you use acrylic paint, since it makes the fabric stiff an fragile. Just apply the paint lightly, and apply at least two coatings.

This is actually pretty cool. How well do they hold up after a wash?

Thanks man for this advice...and great job! DIY!

Saw this new subreddit, figured I'd make a short tutorial, and show off a bit!
