The tube puzzle looks like the "tube quilt" that we made alot of on this board. Put "tube quilts" in the search of this board and you'll find lots of them. If I ever figure out how to post pictures from my computer, I'd show you mine. Super easy and fun to do!!
Also this is a good tute for you to watch
