Yep, this is it...the precut batting to use when you make a jelly roll. To do a full size rug, you will need 2 rolls. Each roll is 25 yds x 2.5 inches wide. Price wise, this is comparable to purchasing a twin size batting with the added bonus of not having to cut it all and only using the seam batting tape to join 1 seam. Jelly roll rug lovers rejoice!
