I use this tape to wrap around spools. The roll has lasted a long time. I use the 1 inch size and then slice it down the center. Two for one works for me.

I made storage boards to store embroidery threads and serger cones in the drawers. Cut dry erase board to fit the drawer, mark a grid and glue on golf tees. I use longer tees for the cone threads. The spools stay in the right space. Easy to take out and put the thread back when done. For embroidery threads the drawer holds 81 spools. I forget the serger cone numbers.
When you glue the tees onto the board just space them so there is room to fit the next spool on the board.
