I bought the pattern and looked at a few you tube videos on some tips and techniques. I started my jelly roll rug yesterday by cutting 42 strips from my stash, (all the same fabric I bought on clearance when Hancock Fabric went out of business very cheap), stitching them together with the diagonal seam, trimming the seam allowance, and pressing the seams open while fan folding into a neat stack. Took me about hour and half. I did a google search for the rolls of batting (they are hard to come by right now so many people are buying them) I found them at Nancy's Notions for 9.99 a roll that day only. I did not bother to cut them on the bias. Hoping for the best. and not wanting to invest $70 or more in a rug I might not be able to pull off. Will post a picture when and if I get it done!
