Oh wow. The best OBW's come from large prints with lots of dfferent colors. This will will be a real winner, I'm sure of it. Keep going. Here is the trick. Put three together and then the other three together. Do not sew the seam across the middle. Lay them out in ROWS and you can sew straight seams. No inset or Y seams are needed. (Half hexagon and half hexagon will come together when the rows are sewn together)
