I use Amazing Tape to hold my thread end to the spool. The tape only sticks to itself so nothing sticky on it. It's reusable forever I guess, still using the firsts pieces I cut. I have my cones of thread in see through thread cone holders. I found them on sale over the years at different online sites I have them stacked on a shelf. I use to keep them on spool racks hung on the wall but they were getting dusty. Nothing is more tedious then dusting spools of thread. LOL
