I am helping a friend with her binding. I use Jenny Doan's tutorial with a 2 1/2 inch binding. I have never had a problem when following the instructions on the Missouri Star tutorial-- https://www.youtube.com/watch?v=0vCWpxBRs20&t=17s
We have joined all strips of binding fabric with no problem. The binding is all sewn on with no problem. The problem started when joining the final 2 pieces. We have followed the instructions, but every time we join the fabric it is twisted. We are sewing right sides together, just as we did with the rest of the quilt. The length is correct. We have tried wrong sides together, right and wrong, etc. Just no luck.
I appreciate any help. We put it away until tomorrow and figured we would start fresh.
