That's a great idea, Sue! If you are using muslin, cotton duck or linen that has not been gessoed, I would imagine that the gesso itself plus a little glue on the back might be enough adhesive. I think you could stretch the muslin as you gesso it, starting in the center with the gesso and brushing outward to the edges. I would think this would stretch the fabric and get rid of the bubbles.
Also, to prevent the piece from curling - the fabric would shrink as it dries - I'd think you'd need to gesso the back as well.
Seems like a lot of work for the first one, to get the technique right, but after that I could see an "assemble line" of mini-canvases, LOL!
I'm so cheap; I love anything that I can reuse! Silly me, I never though of using the canvas scraps to test colors! I do that all the time with my watercolor scraps, duh!
Just a thought; perhaps Elmers dries too hard? Do we need a fabric glue which is a little more pliable? SOBO perhaps?
Thanks for your thoughts!
