Welcome to the Quilting Board!
Amazing Grace, how sweet the sound, that saved a wretch like me. I once was lost but now am found, was blind, but now I see. [John Newton (1725-1807)]
I used fusible batting for small items and recently on two play mats for my grandsons. I lightly fused the layers together then loaded it on my longarm. I wanted the finished products to be somewhat firm, and they are, but I had to continually clean the gum off of the needle with an alcohol pad. I have no plans to use fusible batting again.
I have tried one brand (can't remeber what it was) but I prefer spray basting. The layer stay together better for me.
I have used it on crafty things like tote bags or purses but not a large quilt. I have quilt and don't want the "stiffness" that a fusable adds wheni am stitching.
