I picked a pattern for my block "twisting star" I printed out the pattern and the test box was larger than required. No problem, I made up the pattern on a plain piece of paper making my block 6x6 knowing I needed to put 4 of the pattern together. I cut apart the pieces, traced them on a new piece of paper, adding 1/4" to all sides. I sewed the piece together to form my TEST block and it is to big. What did I do wrong? How do I make my block come out to 61/2".
I would appreciate any suggestions.
