Lightweight Fusible Fleece 45" 986F Pellon#20
I love the versitily of fusible fleece and this weight is my favorite to work with. It gives just the right amount of structure without being SO thick. If you want more heft, just use 2 layers ( or if making a bag, put a layer of this on the outer fabric and another layer on the lining ).
This fusible fleece is one-sided and 45" wide.
