FYI- I'm trimming it with scissors or nippers in one hand and the vacuum cleaner hose in the other. If I've got to clean the Aegean stables, I may as well share the data from the research. Experimented with using electric hair clippers, which worked well, but it was really easy to accidentally clip a seam allowance. Hahaha, now that's rubbing salt in an open wound.
I'm just a little less than half done.
