I have painted on fabric with good results. I stretch the cotton, paint with acrylics and fabric medium mixed, then use the panel as a medallion or however you want to. Tell her to paint with thin coats and allow it to thoroughly dry before using it. I did a denim jumpsuit with mice on it this way and it went through many washes without losing the mice. I do think she would be wiser to make a wall hanging than a bed quilt. I could see it in the center of a bed runner. Momm,yum! Post pictures, pleez!

Don't have an answer for canvas. However, what about cotton fabric. I've painted a few squares with acrylic paints using a textile medium. Also, there is a line of fabric paints available, can be washed and remains soft. I definitely would go in this direction.

I would photograph it the put the photo on fabric

I do not think that canvas will work at all; it is too thick; it would probably shrink or buckle and would not be at all satisfactory.

I do not think a canvas painting would work well combined with cotton fabric in a quilt. However, I have seen beautiful quilts on which the blocks/designs were painted on cotton fabric using fabric paints. In fact, there was one awesome quilt posted on ths board on which someone had painted a variety of highheel shoes. Maybe your friend could check into fabric painting.

I've done that and it's been years since I painted flowers on some old bed sheets and they're still looking good. Fabric medium is the secret. Just have to be careful and not get paint too thick - it sorta cracks when it's washed.
