I just did that, and it was a nightmare. First I used my zig zag stitch--my machine stretched one side and it didn't lay flat. Ripped that out and started to hand stitch the pieces. Taking too long--rip that out. Then I decided to cut light weight interfacing to join the pieces. The directions for fusing said to use low heat and a damp press cloth and press for 10 seconds. 10 seconds get longer and longer as you go along. It ended up needing 4 seams to make it the right size. It needed to be 68 x 93. I was using Warm & Natural and the interfacing was Pellon. I had to do both sides of the join and it ended up taking me 3 days to get it done. I should have bought the tape, but I am too cheap. The quilt is for my DGD, and I'm thinking that I will never get it quilted. Right now, I don't even want to look at it. So much for my summer goal--finish all my UFO's. Hope the next on goes better!!!
