I have used it quite a bit. I find it best to stitch on a quilt that will get used, tossed around, and washed, but not a wall hanging or the like. Make sure it is fused well-especially around the edges. I haven't had any problems on the items I used it on, but I tend to stitch (usually a satin stitch or tight zig-zag) because I like the look of the finished edges.
Also, I never use fabric softener on fabric I will fuse.
