Drafting Question

  Okay ladies I have a problem and I am not a big math person so I am really struggling with this one. I am working on a rag quilt and I want it to look like a Christmas tree. However I can't figure out how to make the half square triangles the right size. I know with a regular block I would add 3/8 or 7/8 depending on the size of the block. With the rag quilt I want the rag appearance to be in the triangle as well so that the tree looks raggy. I hope I am making myself clear I have noticed sometimes people don't know what I am talking about. If my blocks are 6 inches I have to cut them 8 in order to make the rag edges. Then for the triangles I get messed up would I add another 2 7/8 to get it right . So then it would be 10 7/8 cut square and then cut that in half crosswise.
  Thanks for your help.
