I have tied quilts using the methods described above...but recently I found a blog with a different method (I haven't tried it yet, but it looked interesting). Here's a link:

Just click on each of the little pics and it gives you the pick and step by step instructions.
Whatever method you choose, have fun and don't forget to show us your quilt....we love pics.
