Ok now you are ready to trim this block to a 5" size.
Center your ruler so you can trim it and make sure you measure and watch the lines as you decide where to cut.
I usually measure from the center to the edge and after the first cut then I can also use the cut edge to check against to make sure my square is square.
It bugs me somewhat that the points go to the very edge which means when they are sewn into a quilt you will lose those point tips. but I did this one the way the block was done.
If I use this again I will trim it so there is a 1/4" seam allowance or I will see if I can reduce the size enough to have a seam allowance included in the 5" unfinished block.
Thanks and if there are any questions make sure you ask!! Glad to help if you need it!!
