Disappearing Pinwheel Arrow
I like to do a trial block to test my measurements first. I wanted it to end up at 12-1/2 inch block so I did my initial squares at 10-1/2 inches instead of the 10 squares that Jenny MSQC used. I thought a pinwheel is a pinwheel right? Nope, you must get the lights and darks in the same position if you want the finished block to look like Jenny's.
I had to pick out my center after shuffling my squares and resew it. I also discovered that the last seam sewing my rows together needed to be a scant 1/4 for my block to come out at 12-1/2. I thought this pattern with make a great block for a guy quilt in manly colours or a gender neutral for a baby quilt. Here is my block done in green scraps.[ATTACH=CONFIG]562494[/ATTACH]
