Using the Marble bag project on page three as a rough guide, I chose two fabrics that I thought would go together and followed some of the directions they suggest.

I did cut it into strips and sew them together, as you can see.

I formed the bag by gathering one end up. I also created a small circle of fabric to cover the stitching, although I did not find any matching thread so the stitches show anyway...
I also covered the upper edge with a strip of cloth.

Now I'm looking for a good drawstring to sew in and some beads to complete it!
