I'm trying to figure out a way to randomize 324 colored fabric squares. This is a kind of a math question that's technically about sewing.
I would like to, as best as possible, randomize 324 squares (of 14 different colors) for use in making a brighter version of this pixelated quilt
(image is a photo from the book I'm using). I'm using different quantities of each color-- ten of the colors will be more represented than the other four (the quilt will be mostly shades of blue/green/turquoise/teal with some shades of yellow interspersed). The finished quilt will be 18 squares across by 18 down.
I'd like to randomize them as much as possible. For example, one idea given to me was to put all the squares in a bag, shake them up, and pull them out one at a time. Great idea, but the problem is that the squares will stick together. Another idea was to assign each color a number and roll dice. Not super-practical with 14 colors.
Adding to the challenge is the method of putting the quilt together. I'll be sewing strips of 6, and when they're all done, sewing all of the strips together. My plan, once I get the strips done, is to pin them up on a wall so that I can move them around to figure out the most attractive configuration before I assemble the final quilt.
So basically, I'd like to randomize them in groups of six. Not sure if that makes sense. Worst case scenario I'll try to just pick random ones from their piles but I'm biased in favor of some of the colors and am pretty sure I'll fall into the trap of overusing the brighter ones and not using enough of the rest of them. Any strategies welcome!
