I purchased some Deco Bond at Walmart last night, but haven't had time to use yet. I plan to purchase some of the headliner material from Joann"s as soon as I get my next coupon in the mail. I really liked the Pellon Flex Foam I purchased, but think it was an overkill for a pouch---a larger bag, yes, so maybe Joann's headliner will be "just right".
Quiltmaker: Which fusible fleece would you recommend using with the interfacing? Here is a link to Walmart page for the fleece.

I was there last night feeling everything, and there is a wide differential in them.
