I prefer the Pellon product to the JoAnne's store brand but I have used the el-cheapo stuff from JoAnnes (the stuff that sells for .99 per yard) with no problems and bought a full bolt of it because it does what I need it to do for a fraction of the price. I have made a lot of T-shirt quilts. Just don't "man-handle" it and you will be fine. You just want enough stability to keep the T-shirt knit from stretching out of shape when you sew it. I have known people who don't mess with fusible at all, just starch the dickens out of them. I have not tried that but I am sure it would work.
