In all honesty I didn't think there would be that much difference between the Soft & Stable and the fusible fleece I typically use.
I hate it when I'm wrong...
It is a bit pricier than the fusible fleece (which I purchase from JoAnn's by the bolt during a sale and with a coupon for an extra percentage off) but it is well worth the extra cost. Plus it's readily available at one of the LQSs.
The Soft & Stable is much thicker than I anticipated and is actually similar in look and feel to a piece of foam. Despite that I had no trouble sewing through several layers of fabric and Soft & Sable when completing this bag. It made turning the bag a bit challenging due to the bulk it creates but I found a way around that. For this particular bag I simply sewed the interior and exterior pieces together (right sides facing) along the back of the bag only, leaving the front and sides open. I then turned the bag right sides out through my extra large opening, turned the seams under 1/4" and top stitched around the entire top of the bag, effectively closing the opening.
All in all I highly recommend giving this product a try! I will be using it on all of the large bags I make in the future (or at least the ones that need a structured exterior). A huge thanks to ByAnnie's Soft & Stable for letting me test out their product and providing a giveaway prize!!!
