Best Fabric Paint for Pillow?

[crimescene]

Hello! I wasn't sure whether to post this here or another category so my apologies if this is in the wrong place!

I'm leaving to study abroad for six months in just over a week and I just had the idea to make my boyfriend and I matching pillowcases before I go. I just want to do a simple continuous design that spans both pillowcases so I can take one with me and he can have one here. My only issue is that a lot of the fabric paint I have used in the past has left fabric crunchy or otherwise unpleasant (although I've never worked with pillowcases before). I'm planning on getting simple cotton pillowcases but may end up with a silkier material if it works out that way.

Assuming I'm working with cotton or a cotton blend (although I'll take suggestions for all fabric types that a pillowcase might be!), what is a good brand of fabric paint that will result in pillowcases soft enough to sleep on?

Thanks!

I don't know about sleeping on, but I have been happy with the Pebeo Setacolor paints and how they have worn on poly blend shirts.  I gave DH a couple of stencilled shirts in his stocking a few Christmas' ago and the paint has lasted nicely, washing and wearing well.  No cracking, quite flexible, and softening nicely - not that stiff plasticky feel, but with good coverage.  I am going to be decorating a duvet cover and pillow cases myself later this year for our new bedroom, so I guess I'll be finding out.

I've had good luck with Golden Fabric Medium - I've used it on cotton shirts 3-4 years ago and they haven't peeled or faded. You just mix it in to regular acrylic paint to make any color fabric paint you'd like.
