I tried an 80/20 just once, thought it was horrible to work with, never again. Realizing your budget concerns I feel for your frustrations.
Maybe a fundraiser(maybe a bake sale at Fellowship after church services?) to enable the group to purchase a roll of W&N when it it goes on sale(JoAnn's Fabric) at the Holidays?? Thinking it's even offered with free shipping. Just an idea...
