The Workman's that I own has never seen the snaps correctly done. I tried it on a whim once, and it looked ridiculous. Nice thought, just poorly executed.

If you need to "close the barn door", just take the kilt pin and attach the UNDER apron to the inside of one of the back pleats. Don't do the front apron since it may leave a hole... unless you really need to. I have had to do this twice, and it works MUCH better.
