Gads zook. I don't even do one quilt at a time. One at least is always at my sewing machine. Hand work is near the couch. Quilting is at my LA.
I don't enjoy needle turn or hand quilting due to kinda severe arthritis of my hands. So I found ways I can continue to quilt at my own pace.
Learning new techniques is always fun. Except for Cotton Theory - that was pure painful and a friend finished it for me. I go to classes to learn and use my 'class fabric' rather than my finished product fabric as I know I am slower than many others and I am there just to learn and have fun.
I do find I rewrite some patterns so they are easier for me to do. Some pattern makers just aren't good with directions! Great with design but not directions.
