The favorite thing about using foam interfacing is that it is very easy to sew with and it makes bags look incredibly professional.
Foam stabilizers are great because they give your handmade bags body, stability and an overall professional finish. How we avoid those creases. We use Shape-Flex iron to quilt cotton fabrics before we cut - gives our fabrics a more home decor weight and then a more professional looking finish. The first layer you fuse onto your bag fabric should be a WOVEN interfacing. (Shape-Flex) Woven interfacings are woven just like your bag fabric and will therefore MOVE with/the same way your bag fabric from all that usage. They are a MUST in bags, in my opinion to eradicate that bubbling and separation.
