This fabric is premarked (with fade away dye once the fabric is washed) with dots at 3mm intervals, making it super simple for you to mark in your own choice of pattern. The "dots" cover a 10" square on a 12" fabric (so 2 inches of border) and there is a 12" piece attached without the dots marked for your back. So the actual fabric measures 12" x 24". Available in indigo blue, white, taupe and an almond/biscuit color.
