Where it is used

p. 1

Reinforce the left side seams where the zipper goes on the left front bodice, front skirt, and back skirt with straight-grain fusible tape.

After fusing, compare the seam lengths on the fabric pieces with the seam lengths on the paper pattern to ensure they match perfectly.
