If you use a match from a foldable pack you can push the matchstick into your thumb using your index finger. A lot of the time it'll stick to the back of your thumb really well, also you can help it by pressing it again throughout performing the trick. The reason to do it this way is because you can hand the stick to someone in the audience after you perform the trick and tell them to make sure there is no glue or sticky substance on it. It's a great little trick.
