This fabric is premarked (with fade away dye once the fabric is washed) with dots at 3 mm 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.
