About the pocket:

Size: 12" deep, 4.5" wide (wide enough to stick your hand in if something falls to the bottom.) My wand is 13.5" long, but since it tends to sit diagonally in the pocket, 12" is plenty.

Location: Inside left breast of the robe--the perfect spot for a fast right-handed draw! I figured out where to put it by holding the wand inside the robe while wearing it, trying to find a place where it would "nestle in" and not poke me or look strange. Even while the robe is fastened, it is easy to reach in over the fastening and pull the wand out.

Type/Instructions: I made the pocket according the instructions for a wash welt pocket at vintagesewing.info, which is one of my favorite resources. Note that you have to have access to the back of the lining to make this kind of pocket--the best thing would be to put in the pocket before you attach the lining to the robe, but I just reached up through the hem, and that was good enough. If your robe has the lining sewed to the outer fabric at the hem, you won't be able to do this--there are simpler pockets that you could do, though.

Pictures: It's kind of uneven because I'm really sloppy at hand-sewing. :-p Also, these are my usual cheap scanner pics--someday I will get my digital camera repaired, and then you will all be so impressed.

The label: I made this graphic and printed it out onto an iron-on transfer sheet. Then I transferred it onto white fabric, and sewed it on. I have a nice men's suit jacket (Pierre Cardin!) where the shop has their label sewed under the inside pocket like this, and that's the look I'm immitating:

This was a pretty quick and fun project, and I think it came out awesome. :-)
