A quilt block on paper is used to make the block. You actually sew according to the numbers labelled on the block. Start with !,2, etc. That way you sew by number. Place#1 piece of fabric wrong side down on back side of printed block. You have to hold up to the light to make sure it covers the section. Place # 2 wrong side up ( make sure it is large enough to cover space #2 and flip over and sew through the paper and the 2 pieces of fabric on the first line. Move from # 1 til the last number on the block. I trim seam allowances to a quarter inch after sewing each piece and iron each piece after sewing. When you are done, the finished block will appear right side up on the back of the paper. Then, carefully teasr away the paper from the block.
