This one was by far the most difficult for me. I assembled it last night after I got home from work.
I matched the darker colored hexagons fairly well, but the light blue was definitely about 1/8-1/4" off.
You sew rectangle units and then sew those together to form the hexagons.
4 hexis in total in this little sample piece.
Maybe when I did the trimming of the individual rectangle units, it threw my measurements off?
It was still fun though. Just working with scraps. The colors are cheery together.
