Yep, I just used the acrylic paint on the fabric, no stabiliser or anything. Here is a (not very good) picture of what it looks like after a few washings:
bethimusprime - I haven't tried anything other than the acrylic paint. I did
start using fabric paint on the very first ones I did, but the color wouldn't show on black fabric, and it looked like it'd need two bottles of paint in the end, so I immediately moved on to acrylic, and with these I didn't even bother trying the fabric paint. If you have a light-colored fabric or dark paint, though, I'm pretty sure fabric paint would be better and more long-lasting.
