I saw this tip on Pinterest: http://thatsmyletter.blogspot.com/2011/12/s-is-for-sister.html (original blog post). The first time I tried it this way, my wreath broke using the bread knife. I was still able to use 1 side of it but I was disappointed that I didn’t get my 2 for 1. The next time, I bought a Foam Tool package kit and it turned out great!
What you need: A foam wreath (if you buy it at Hobby Lobby or Michael’s make sure to use a coupon to save even more!); Foam Tools Kit (again use a coupon) and a Bread Knife (optional).
Step 1: Take the foam wreath and the scoring tool (the one on the right) and in the center of the wreath make an indention and go around the entire length.
2. Taking your cutting tool (the center tool that looks like a knife) and place it in the center of the scored line you just made and start cutting. Gently cut into the foam turning the wreath as you go. As you go around the wreath multiple times, your cut will get deeper and deeper. Once you get over 1/2 way, you could use the bread knife, but you’ll need to be careful because too much pressure and it will break. I used my foam knife the entire time and it worked great. I did have to take breaks because my hand got tired.
3. Eventually your foam knife will break through to the other side and just continue around the wreath until the whole thing separates into 2 wreaths. Take the filing tool (the one on the left) and gently file down the edges on both wreaths. This is a great way to save money and get 2 for the price of 1!
