Broken cone~
Thanks for the suggestions. I was able to cut off the mess, just kept pulling cut ends and pulling cut ends till it quit, and I was lucky to find ONE end! Turned the spool over, made 4 bobbins - very slowly - and I now think I can use the rest of it. I didn’t really lose too much, at least I didn’t lose the entire cone. I added about an inch of cardboard tube into the spool, and it worked. Spent about 15 minutes is all. But YAY didn’t have to toss!
