For larger nail holes, you can use a similar method as above, but the crayon will stick in the hole better if it’s just a little bit more soft and malleable. So take a lighter and warm the crayon, just a little bit. Be careful here. You want it just a little softer, but not dripping all over the place. You certainly don’t want hot wax dripping all over your hand. Then rub the soft crayon over the hole. Wait until the crayon in the hole sets. Then you can rub off any excess with a dry rag.
