I have always avoided Y seams (those angled seams you get such as when you join three hexagons together). At some point in the last month though I seem to have decided the time had come, and so I started cutting out fabric for a runner to go along the top of my chest of drawers.
Hexagon Calculator to work out how many I'd need of which size. Then I drew one and made a cardboard template. My template showed both the outer edge AND the line I was going to sew along. I know you can buy things like this but making your own means it's available to you the instant you want it. Having cut out my hexagons and drawn the sewing lines on the wrong side, I was ready to go!
Last weekend I was once again cat sitting and Luna was on fine form.
