By the time I get to the FMQ part, I usually start a new quilt so I have my hand applique work to take with me to work on while I'm out. So when I get too frustrated with one, I can always switch to the other. The only time I would really push through would be if I had a deadline for a client. Quilts for family or friends are usually a little late because I refuse to keep working on a quilt to the point I hate it if I'm going to have to see it over & over again every holiday.
