Oh, I'd also be interested to know... I use acrylic. When I painted my jean jacket, it's not that ruff. When I paint my t-shirts it's not that ruff, but the paint cracks a bit.
have you guys tried fabric paint? i've never actually painted stuff..... i just sew things on to other things lol.
or is it acrylic fabric paint you're using?
i'm not really sure if that helps at all...!
O.o
I use acrylic and it work great for me.
Maybe try something oil based? And permanent.
...if they make that permanent. I'm sure you can find something.
Acrylic is basically fine melted colored wax xD
Or go to a fabric store and ask someone, I'm sure they'll know something.
