I save used matches and snip off the burned ends. The resulting wooden sticks have many uses, not only relating to glass crafts.
For fused glass work they’re a cheap and disposable means to apply glue (such as Bullseye’s Glastac) when assembling a piece, they’re useful for gently move small pieces of glass around and to apply epoxy resin to bails. For fine work you can sharpen the end of the matchstick with a knife.
For traditional leaded glass work I find matchsticks useful as a soft and disposable scraper when cleaning away excess leaded light cement to get a nice neat edge.
