I have 21 participants so far -- I'll keep things open for another week or two, but be sure to get in touch if you want "in" for 2017 and you're not already on the list at the right side of the blog.
In the meantime, start thinking about your center block. it should be no bigger than 9"x 9" or 8" x 10" and can be smaller if you wish, or some other dimensions as long at it's not more than about 80 square inches, finished size.
As before, please don't use any fabrics that can't be ironed or that will ravel a lot, or will cause problems for sewing/quilting (if you want an exception, contact me -- I've approved one so far.)
Your choice of block and fabric should reflect the sort of quilt you want at the end, although there are no guarantees!
