I laid out the 210 hexagons I had already made, but I was short a few. I quickly basted a few more. After moving and changing things around for most of the day, this is what I think I’ll go with.
I plan to make a tie and attach it to the top. I’ll need to make 50 or 60 more hexagons to back the edges, but that can come later. For now, I’ve started stitching the greens together.
