You will need:
foam core board (mine is 3/16in)
an old book
rotary mat (or cardboard) for cutting
Here's how my project turned out. The first thing I did was choose my font and sizing on my computer. I tried not to pick a font with too many curves because I knew that would be very difficult to cut out. After printing out a copy, I traced it onto my foam core board. It's very simple: just lay the printed sheet onto of the foam and trace with a blunt object (I used a pen). This will leave an indent which you can use as your cutting line.
Put your foam on your cutting mat or cardboard and start cutting. I took it slow and didn't try to cut the whole way through on the first go around. It took a couple of passes to go all the way through. Don't worry about your cutting lines being completely perfect, it gets covered up anyway.
Kristin and I was very excited to give them to her for her birthday.
Happy Birthday Krit!
