Step-by-Step Sew Easy Instructions

  1. Use ruler to mark an X on wrong side of each patch at intersection of ¼” seam allowances. Mark a dot in center of each X
  2. With right sides together, align first two patches. Join patches by stitching from dot to dot and backstitching at dots to secure seam at both ends. Press seam allowance to one side.
  3. Aligning dots, pin third patch to unit. Stitch from center dot to outer edge. Press seam allowance to one side.
  4. Carefully folding unit out of the way, if needed, align dots of third patch to adjoining patch; pin at dots. Stitch from center dot to outer edge to complete unit.
  5. Press seam allowance to one side. Repeat to make additional units; sew units together.
  6. In same manner, set in any additional patches to complete block.

TIP: Except for the outer edge of block, always stitch from dot to dot. This will keep seam allowances free to allow you to set in pieces.
