Step 1

Pin tucks. Prepare fabric with pin tucks for piece #1 (see related techniques). We made our pin tucks 5/8” deep with 1/2“ spacing between them. Note that the pin tucks on the left and right sides should be going opposite directions.
Cut out 4 collars, 1 placket, and two front pieces. You also need a 24” strip of 2“ wide bias. Interface one pair of the collars.
