I am trying to make my MIL a quilt for her bed, and I have some Christian panels to also use in the quilt top. The rest of the top I would like it to be a D9P.. The panels are 16.50 x 16.50. Would I make each small square 5.75? That would be 5.75 x 3 = 17.25 - 2 seam allowances for the first sewing = 16.75. Then minus another seam allowance for the second sewing = 16.50 Did I do the math right? Some day, I hope to get as good as all you sweet people on this board. Until then..I am enjoying my journey along the path.
