I've been working on some hexagons, inspired by this quilt, using up fabric I already had in some muted, modern colours. I don't have a pattern, but I do have a ruler with a 60 degree angle marked on it, so I studied how other people had created hexagons and off I went.
For each segment of a hexagon, I'm sewing a 60 degree triangle to a strip of fabric, then trimming the joined pieces into a large 60 degree triangle. Then I sew three of those together to make a half hexagon. Eventually I'll lay out all of those how I want them in the quilt, and join them into vertical strips; then when the strips are joined, the full hexagons will appear without me having to sew complicated Y seams.
And to finish here's a trial quilt layout, with some sage green chambray fabric from Village Haberdashery (London)
