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?
