I have not made as many tshirt quilts as some of the others have, but I have made at least 10. I have used a few different interfacings.
Now I am using Therm o web heat'n bond non woven lightweight fusible interfacing. The "bond" is quick and sturdy and I don't have to use a pressing sheet. I am working on my 3rd tshirt quilt with this
[h=1][/h]I feel like a got a good price on Amazon. I will be using this again
