I believe you can. I recall seeing them do it on the Cricut informercial. I'm not entirely certain of how you go about doing this, but I think you maybe iron it to WonderUnder so that it will have more solidity to it.
You can cut certain fabrics on the cricut. You have to iron something on the back like an interfacing. Sorry, I can't be more help. I know they do it for apple on th infomercial.
