I use all Pellon products, but feel free to substitute with other brands based on the description.
Pellon Thermolam Plus (Fusible Fleece)
I use this lofty fusible fleece in bags that I don’t want to maintain a stiff shape, but want to have body, such as the Dallas Vintage Duffel. Think thin quilt batting. It’s easy to use, very light, and not too expensive considering it’s double the width of the other interfacings listed. It will hold some shape though, so don’t use for something you want to slouch. You can use regular Pellon Fusible Fleece as well. It’s a bit loftier than Thermolam, which has been needled and is denser.
Pellon ShapeFlex SF101 (Woven Fusible Interfacing)
For everything that doesn’t get the aforementioned interfacings (pockets, linings, etc.), I will use this interfacing. This is good for slouchy applications where no stiffness is needed, just more body and “bought in a store” crispness. Basically making a quilting weight more like a home decor weight. I use this for the entire India Hobo Bag.
I was late to the game in trying foam interfacing because of availability, but once I did, I was hooked! This makes a nice structured bag that stands up on it’s own, yet is very easily manipulated unlike the stiffer stabilizers like Peltex. The pliability makes it a breeze to sew. It’s usually sew-in and not fusible, so you will have to either baste it to the exterior fabric pieces, or use a fusible web, like Pellon Wonder Under 805.
