My mom is wanting to make a D4P quilt and I'm trying to help her figure out how much fabric to use, but for the life of me I can't seem to find information about the finished sizes of blocks. I did find that if she were to use 5 inch squares, the block would be 8.5 inches finished. But that is too small of a block for what she is wanting. If she were to use 8 inch or 10 inch squares, how big would the finished block be? Thank you for the help.
