Pattern matching on men's shirt sleeve plackets

Close up of the placket for McCall's 2447 -- This pattern calls for the single piece sleeve placket (rather than the Pam Erny's two piece technique). For me, it makes it a real brain twister to figure out how to cut the placket to make sure it aligns after all the sewing, folding and turning inside out to match up on the right sides. Yay, though, I did it!
