There are plenty of tutorials available online. Basically, you start in the middle and keep zig-zagging around until it is the size you need. It tends to start the bowl shape on it's own. I had to concentrate on trying not to pull too tightly as I stitched until I got the flat bottom finished. I controlled the shaping by pulling the cord slightly as I stitched.
When you get to the end, you have to decide how to finish off and tidy up the end of the cord. Just use your imagination!!
I had about 4 yards left after making my first 3 bowls. I couldn't stand to let it go to waste so I made a couple of coasters. I gave them a little steam press so that they are nice and flat.
I'd like to try dyeing my next batch of baskets. I see another trip to WalMart in the near future!
