I made my first tshirt quilt last year and have another for graduation to make this year. I used a soft stabilizer that you can iron on. One piece of advice; when fusing the stabilizer onto the t shirt don't make the same mistake I did which was to try and iron on the front of the t shirt. It smeared the writing. So, I turned the t shirt face down, put the stabilizer on the back side; sprayed with a little water and ironed. They came out great. Also, one more thing I learned; don't cut the actual square you want until after the stabilizer is on. The first time I tried I cut out the square and then put the stabilizer on. Well the t shirt curled a lot on the edges; so I then cut out a larger square from the t shirt and a larger piece of stabilizer. Then I went back and cut the actual square after they were fused. That worked much better. I made this for my friend's GD. She loved it. Good luck and I hope the advice helps.
