I have a square ruler for every size of unfinished quilt blocks I make. I like to put the exact size on the square and it's so simple to see exactly what needs to be trimmed. If the block is smaller then the ruler I know I messed up somewhere. My biggest square is 20 1/2" and my smallest is 2 1/2". I seem to use the 12 1/2" and 8 1/2" the most. Olfa has a 7 1/2" square ruler that I have used more then I thought I would.
I have both sizes of the Block Maker ruler and it is essential for squaring up blocks when I have to use the blocks made for a quilt, example Friendship or Swap blocks.
