it's all upholstery fabric - kind of ultra sued-ish. I think stretchy wouldn't have kept its shape very well. The fungus is kind of like velour.... something I randomly picked up in the remnant section about a year ago. The underside of the fungus is leftovers from the back of a pillow my son made - its horrible cheesy faux suede, but PERFECT for fungus! LOL!
I would agree! They are very well done and that counts big time when you are pricing! I know it depends on the people who will be buying, but $5-$15 sounds completely reasonable to me! Good luck to your daughter in her fund raising efforts!
