I saw this on Pinterest and I knew I had to do it. I'm so tired of my bobbins being such a tangled mess! It took 3 Lowe's employees to help me find the tubing I needed. And each of those male employees looked at me with a blank stare when I told them I needed the tube for sewing!
I found it easiest to cut the tubes with my rotary cutter and then the slit with scissors.
I'm so happy with my untangled bobbins!
