This pre-cut batting makes Jelly-Roll rug making a lot easier!
NOTE: The Featherweight is fine to use for the straight-stitch steps in your jelly-roll rug construction. However, you will also need another sewing machine that can do a zigzag stitch. (A Zigzag attachment will not even be adequate due to the bulk of the batting.)
One roll will be enough to make one rug measuring at least 27" wide by 41 1/2" long, with a little to spare. Roll of strip-batting measures 2 1/2" x 50 yards.
