How to remove excess glue from around the edges of paper? To make a post card, I like to stick small pieces of paper on a card. I put glue stick on the whole paper, because if the corners don't have enough glue, it will not be strong enough. However, when I stick the paper on the card, often some glue comes from beneath on the card.

What tool can be used to remove glue stick?

I have seen people use a cotton tissue, a toothpick or a craft knife. What are pros and cons?
cotton tissue: I find this to be the most messy option, since it's difficult to regulate where the glue ends up, which means you might get glue on places where you do not want it

a toothpick: The sharp point might damage your paper if you press too hard

craft knife: might make your knife dull!

I mostly use thick scrap paper (or craft sticks) to scrape the glue off and haven't had any problems with that.
