Take a look at a liquid stabilizer like Terial Magic. You spray it onto the t-shirt and when the fabric is damp, you iron it dry. The fabric stabilizes and becomes very easy to cut and sew with. After the quilt is complete, you can rinse or wash the quilt to relax the fabric back to it's natural softness.
