I was told that when I got my 1st embroidery machine in 2000. I try to remember to do that but it doesn't always happen. Seems like such a waste of thread to me but what the heck, the price of repair is more. As I always seem to have trouble threading my sergers plus its a pain to thread the quilt machine I tend to cut at the spool and tie on the new thread, pulling the thread thru to the needle. I figure it I'm going to waste the thread I might as waste it with a purpose.
