Perfect lapped seams
Added Oct 5, 2013
Cut all your pattern pieces to include the 5/8 inch seam allowances. Place the two pieces that will be joined/lapped (ie: front bodice joining back bodice at side seams) right side up (the piece that will feature the exposed seam is facing up) - that will be referred to as the 'outside flap'.
Take the outside flap piece and trim 1/2 inch off of the seam allowance using a rotary cutter and straight edge ruler.
