I used the ponytail holders also. then someone I think on here posted an idea about using clear plastic tubing. it's 3/8"-1/2" dia. tubing. you slice it into 1/4" slices then cut a slit through it up one side. so you have a ring that is split. the split slips over the bobbin and closes around the bobbin. you can still see exactly what color thread is in there because it is clear tubing. I bought 1 foot of tubing for 60 cents. makes approx. 48 holders. It's a pretty neat idea and they aren't as bulky. Mary
