lfw045 - Thank you for the link to the video, it was helpful - if I can't figure out how to do the continuous bias strips, I'll do it that way.
Thank you Izy and Marcia for your links - It's at step 4 that I just don't get. After moving over one line, I just don't get how to align the pins and raw edges and lines.
I think I've got a mental block! I don't get it!!! If I could actually see it being done, I might get it then!
