Earlier this year I made a map case for a fellow and just before the holiday crush he reached out to have a similar case made with two changes: it needed to be 29" long instead of 19", and he wanted a luggage handle installed on the body. I found what I thought were the photos from his original order and pulled the aesthetic specs from that.
It turns out I made two 19" map cases back to back and I'd grabbed photos of the wrong one for the specs. So I'd made the case in the wrong color and didn't include some decorative stitching around the periphery. Even worse, I didn't figure this out until the client received the case. That was pretty embarrassing. I redressed the situation by producing and shipping another case as soon as the holidays allowed.
