I love mine. I don't remember seeing arag quilt block. I would assume it could be done though. The quilt blocks that it does have are great and you can resize them along with having it draw the 1/4 in seam that so many have a problem with. You can chose to use any seam allowance. I've but fabric, leather, vinly, construction paper, etc with it and have no problem. I like that I can put any design on it, I don't have to buy dies. I have the rag quilt die for the accuquilt and it works great.
