Need Help Squaring Up an Odd Sized Block
I am making a 5" Ohio Star block. I have made the hourglass blocks (quarter square triangles) with nicely matching center points. I am trying to square them up to 2 1/4". I am using a 2 1/2" Omnigrid square ruler. I have used blue tape to mark the 2 1/4" lines. I can't identify where to mark for the ruler to coincide with the center of the block. My attempts at squaring up the blocks have resulted in uneven "points" for my Ohio Star. Any help,advice, tips, tricks, etc. would be greatly appreciated. Thank you in advance!
