Big Fat Yarn (BFY) is yarn reinvented—no tools, devices, glues, needles, hooks, or mess involved. Everything is done with hands and results are in minutes, not hours. Unlike spun yarn—which pills, frays, splits, and shreds—BFY is indestructible and can be ripped out and transformed as often as kids want to try something new. No prior skills necessary. Great family activity with projects for everyone 4+ years old. Turn Fat Strings into ANYTHING!
