Just one comment. "This ain't woodworking buddy"
Due to a multiplicity of events yesterday, I didn't get to start cutting for my first quilt. I did, however, between MD appointments, get to pattern out, cut and sew an arched end dust cover for our hand crank 99K. What was that now?? Oh yeah. 3.1417 times the diameter divide by two plus the side length doubled plus 1/2 inch for seam allowance on the ends and 1/2 inch to the width for the hem. Took a few moments with a calculator to figure the length of the wrap. Sewing the arches was a chore and I can't imagine tackling an inset sleeve.... sheesh. Plywood doesn't crawl ya know. Don
