Indigo is really the color of the month for the Rainbow Scrap Challenge but short of that we can substitute black and gray.
I've been making Dresdens each month in color of the month, color of month with b/w, color of month with w/b and color of the month with it's complement. Since I'm substituting black and gray for indigo it kind of made it difficult to make four blocks according to my usual plans but I did my best for substitutes.
Above is the b/w with white.
And here we have gray with b/w and w/b and w/b with black.
I've been making these 3 inch spools for a couple of years and have plans for a very large quilt with no borders. I think I need 783 and have 564.
Join us each ScrapHappy Saturday - linky for the Rainbow Scrap Challenge.
