in fusible fleece, fusible web and fusible interfacing. I am doing the bow tucks purse and it calls for pellon fusible fleece. I have web and interfacing. Can I use one of those or would it not be as sturdy

The difference has more to do with the thickness of the fusible fabric than with sturdiness.

The fusible web would be be the thinnest, the fusible interfacing would be of medium thickness and the fusible fleece would be the thickest.

It's really up to you which one you choose to use.

Fusible web is a heat-activated sheet of glue - it looks like a misty fabric, but not woven, and when you iron it between two pieces of fabric according to the directions, it melts and fuses the two pieces together.

Fusible interfacing is also non-woven fabric with one or both sides coated with the heat-activated glue. (there may be woven fusible, too, but I can only remember seeing the non-woven type) It's used to stabilize and shape fabric, mostly in garment construction and things like tote bags and fabric baskets and such. It comes in many weights from - barely there to heavy stiffener. There are many woven and non-woven interfacings which don't have the fusible stuff - they're intended to be sewn in.

Fusible fleece is fleece that has the heat-activated glue on it. You would use it to stabilize and pad fabric and looks beautiful when you quilt it. It's not as thick as the fleece that you would make a blanket or snuggie from, but I think it's denser. I only have one kind of fusible fleece and I think it's about 3/16" thick.

good information!! I always wondered too

Love the things that I can learn from this board.
