The only thing you are going to need is a computer which you undoubtedly already have, a printer, and some printable paper. Now if it's something like a template that needs to be on the thicker side, you might want to consider buying heavyweight paper for these projects. Heavyweight paper is very durable and usually about .006" depending on the actual weight of the paper. Whereas with something like regular printer paper it's about .002", again depending on the weight and type of paper.
This might not seem like a difference, but in the scheme of things its like comparing apples to oranges! This heavyweight paper is going to be considerably better these arts and crafts projects as far as printing goes. Also, you can choose from a variety of custom stock sheets and custom paper size options as well. Need something a little larger for a template? Or maybe something a little smaller to make your own cards? No problem, we've got you covered!
