I just found your question. I used to use the pony tail elastics until today. I ordered "Hugo's amazing tape. It is not sticky but is reusable. It comes in 1" x 50' or 2" x 50. You cut to what ever length you want. My spools look so neat now. I used probably 30 ft of it to do all of my spools.
What a good idea . I just started using Amazing Tape. It works well also . Here's a flower for you.
I haven't purchased the Amazing Tape, but it was demonstrated at one of the sit and sew lessons I attended. * to U 2
