Each year the Tokyo Quilt Festival exhibits lots of Partnership Quilts, which are made by quilt blocks submitted by everyone. A theme for partnership quilts is set by a popular Japanese quilter/textile designer annually, and she will put all blocks submitted into groups. Folks there will piece all blocks and make them into quilts accordingly.

Check out Ayumi's post for all the details on dimensions, where to mail them, etc. And join this flickr group to see blocks made by others, and post your own! I plan to take part - will you?
