Clever tip but I must admit during this pandemic I have not used nail polish. With all the hand washing, I have been slathering on the hand cream instead.
Just thought of another idea that I use and that is for packing around my Featherweight when traveling. Thought of it when reading that post about Featherweight cases.
Great idea! I use mine for thread catchers, at the moment I a removing some appliqué pieces I didn't like, so have a chunk sitting beside me, saves me from wearing all the thread.
I keep odd pieces next to my machine and use them to catch threads and small scraps.. I also use them to pick up stray threads off my sewing table and floor. They do a great job.
