Chris in Kentucky requested a white on white center with black on white and white on black strings. This is an often requested color (or lack of color) combination. It is a combination that makes a very striking quilt.
Linda in Wisconsin had a similar request but with a twist. She wanted a bright yellow center string. In addition she wants one skinny yellow string 1/4" to 3/4" wide only on one side. This should be an interesting quilt and I hope I get to see it completed.
