4. Cut a strip of 1⁄4-inch-wide lightweight fusible web tape, such as Lite Steam-A-Seam 2 for both placket edges. Finger-press the strips, paper side up, to the right side of both column outer edges. On the tall column, the fusible strip should stop 11⁄4 inches from the top edge. Press with an iron to fuse the web tape to the placket.

5. Remove the fusible web tape's paper from the inner column's edge. Fold the edge along line 1 to the placket's wrong side. Next, fold along line 2 and bring line 1's folded edge to meet stitching line 3, enclosing the seam allowance within the column. Finger-press, then fuse with an iron.

6. Topstitch along the inner column's outer edge from the cuff end to 1⁄4 inch below the top. Pivot, and stitch across the column to just past the vent. This encloses the clipped inner triangle and helps the placket lie flat.

7. Flip the tall column right side down over the inner column. Remove the fusible web tape's paper from the column edge. Then, fold along line 6 to turn the edge to the placket's wrong side.

charbroiled writes: This works very well with crisp/firm fabrics. I had a little trouble working it on a brushed cotton though - too soft I suppose.
Also - I discovered that when converting a continuous lap opening to this placket opening it increased the sleeve seam length by about 1 1/2 inches. It no longer fit the cuff seam.
Adding/increasing the pleats looked bad, so I gathered the excess to make the seamlines match.
Redrafted the sleeve to remove the excess for the next time.

whoneedlesthis writes: I used to make my shirt sleeve plackets in two separate pieces, until I was altering sleeves on an expensive RTW shirt and first saw this one!
Once I changed to a one-piece placket, it looked so much more neat and professional.
Thankyou for including a printable pattern piece for us, now all my shirts and blouses will look fabulous!!

LeahBoyan writes: I've used the placket pattern from David Page Coffin's book and love it! It is flawless. I have altered the pattern slightly to increase the seam allowance. This helps me in two ways: 1) it's easier to turn under 1.25 inches rather than 1/4 inch, and 2) the seam allowance acts as an interfacing to give the placket more body. I alter the seam allowance on the 'right hand' side (the one with the #6 fold to 1.25. The 'left hand side' I increase the seam allowance to .5.
