First I cut out a little paper heaxgon.
I then pin it onto the fabric and roughly cut around it.
Using some thread, I sew the loose ends over the back, pulling out the pin in the process. The piece of paper is still in there and it gives it some structure.
Then I place two pieces with their nice sides together and stitch over the edge.
Instead of attaching them straight to the big piece, I make these little flower shapes instead, with one of the turquoise ones in the middle. This isn't a full flower because I was filling the last edge. I then attach the flowers to the big piece and fill any holes with the dark blue pieces directly.
Done! I unfortunately didn't have any american coins but I think you get the idea.
305 hexagons make up the complete piece.I'm just not sure what to do about the edges. To you people with papter stichting experience out there: I want to attach a strip of fabric to the edge. How do I do that?
