Welcome aboard, so glad you found us. Is a great place to visit when you need people who understand the desire to cut up perfectly good fabric...
I started quilting (or at least piecing) quite young, when I was still a teenager. It has been my hobby now for (sigh) 50 years!
Not sure on your frame, but that's a lovely piece. I'd be looking at "Amish" makers, judging by the peg and jointed construction. But something like that didn't usually come with much of an instruction manual.
