Spaced tucks are folds of cloth sewn at regular intervals to add texture and interest to a garment. Sew them in groups and down the full length of the tuck, or leave them free at one end. Use vertically on a bodice or yoke, or horizontally around the bottom of a skirt.

Mark the position and size of the tucks onto the fabric’s surface.
Fold the fabric along the lines with wrong sides together, and press with an iron.
With a straight stitch, sew parallel to each of the folded edges to form the tucks.
When all the tucks have been completed, press them all in the same direction.
