Sew your own custom rug, an approximately 30 in. x 44 in. oval area rug, using one precut fabric strip roll (42 fabric strips that are 2.5 in. wide), and 100% cotton batting. The Bosal Katahdin batting roll comes precut to size, and coupled with the Jelly Roll Sasher makes the task easy! This Jelly Roll Rug pattern by Roma Lambson of RJ Designs requires a sewing machine that will make at least a 5mm wide zig-zag stitch.
