I use June Taylor fusible. I buy it in the largest size and cut it to size because it is much cheaper. BUT, it is not evenly distributed (the quality isn't that great) so I use it for smaller things, or for children (my g-kids love using their quilts for forts, or as transpertation vehicals for their pets). I still like it because it is so easy to use, making the quilting part go so fast. I don't use it for large quilts or wedding quilt types. Joann's used to sell it (don't know if they still do because I haven't bought any in the last year or more).
