I googled it and was able to make this for the Relay for Life. I'm ready to try it again.
I'm not sure where these directions came from, but I am NOT taking credit for them.
Cutting fabric with cricut
1. I used 100 cotton poplin fabric, but you could use anything that is cotton. Pre-wash your item with NO fabric softener and with your fabric. After you have washed your fabric, adhere Heat-n-Bond to your fabric. DO NOT USE PELLON....IT DOES NOT WORK!

It is too "stringy" and will stick to your mat. Okay, enough of that. You can get Heat-n-Bond in the fabric store, or they also sell it in the crafting section at
Walmart pre cut (near the sewing notions". Do NOT let them talk you into Pellon.
2. Peel the paper backing off the fabric and adhere it to your mat. Take your scraper thingy from the tool kit (I'm so professional!) and smooth it on the mat nice and tight. This will ensure that you will get good clean cuts. This is a VERY important step.
3. Here are the settings for your machine. Put the blade on 5, the speed on the lowest and the pressure to max. This will ensure that you will not go too fast and pull your fabric. If you have made sure to rub your fabric really well on the mat, this should not be a problem. I suggest using a NEW BLADE if possible. In fact, I have a "fabric" blade that I use only when I cut fabrics out.
4. I cut my images on portrait mode on the Expression. Most of them were 8-10" high. I tried to use the least intricate designs as I could, but one of the boys HAD to have a tiger. (You should have seen 5 boys piled into my craft room rummaging through my Cricut stuff!) On his, what I did with the tiger, and the Zebra for that matter was to cute the "shift" version, or the shadow version. On the Zebra, their shirts were white and I cut the Zebra in black on the shadow (shift) function and it worked out great.
5. I also practiced on paper first to make sure that my sizes were good. I bought the t-shirts at Walmart for $4.50 a piece in the men's section. They were Hanes 100% cotton and worked great. Honestly, the hardest part of the whole thing was figuring out the settings and which bonding material to use. After that they went really fast.
