I wanted a take along project and also thought of the GFG. I found this link to Brandy's. You buy mylar pieces (available in many shapes), they have a hole in the center and you get a little pop stick. You put a running stitch around the edges, pull up and on the the next, when you sew a couple together, then you can pop out the middle ones and reuse them for more hexagons. These can be a little expensive to get started, but you can use them over and over. So far have made a table topper. Love these!

On the other hand, am also working on a tumbling blocks hanging with the regular paper pieces that I got from paperpieces.com where I also got the pattern. I like that too, but know that I will not be able to use them again, and it is harder on the fingers.
Good luck, and remember we like pics!
