I could see this using the Home Dec rolls that some stores (like Hobby Lobby) use to display Home Dec fabrics. It is round but would be a free way and safer (maybe - no splinters) to roll the quilt on. They are wide - 60' if I remember correctly, but could duct tape 2 together for larger quilts. (They will give them to you for free if you ask and they have them) I will try glue basting next time!
I just bought 10 yards of batting at Joann's and they gave me the big round tube and now I know what to do with it! Thanks for the tut and for the tip on using this big tube!
