Jenniky - this is an interesting method but I think I'm a bit confused (my brain - not your instructions). Let me see if I understand .....
These connecting strips / sashing are wider than a typical sashing (say more than inch or so). Because of this, I need to "create" a quilt sandwich section.
I attach the front sashing and the back sashing like the 1st method. Where I got confused -- is the back piece folded like the 1st method than stitched down? if so, is the folding really necessary? or can I just fold over a small section to create the finished edge. After that, I do the quilting on that small sashing section?
I'll have to try this on a scrap and see if I'm understanding it but my brain just isn't processing it. That's the problem with fibro - it messes with the processing center of the brain. Learning something new is VERY hard but once I've learned it, I never forget. Weird, huh?
