Measuring up to mark the eventual hemline -- you don't want the pocket seam allowance to be longer than this.



Fold the vest front out of the way and sew around both sides and bottom of folded pocket patch.



I sewed around twice for strength, then trimmed and graded seam allowance.



I slipstitched the lower edge of pocket opening to the inside layer of welt, both to help hide the raw edge of welt and to help the user (that is, Bob) to more easily slide a hand into the pocket. Otherwise, you might get hung up in the little area between pocket and welt.



For final pressing, I cut another piece of cardboard to slide beneath welt, just to that line of slipstitching. Helps to prevent the different layers beneath from leaving press marks on the outer welt.



Finished pocket, with pretty good yellow and white alignment. It looks better in real life than it does at this angle of photo. But boy did those greys get out of whack! Not at all sure how that happened. Hard to see here, but the grey aligns pretty well at right-hand end -- just in the center that they look drunken. Oh well, my hope is that in real life the white and yellow will carry the day and nobody will see the greys. . .



There sure is a pretty pocket hidden underneath!



One done, now lather, rinse. . . OMG, I have to do this again?!?
