Error on what I said earlier, sorry about that! Looking at the white part of the block, it appears to look to be 5.5" after sewing your border on, so the original white block was 6 inches. It will take a 3/4 inch border sewn on all sides for you to end up with a 6.5'' unfinished block. Once sewn you will only have 1/4" border around the block.
