If you used a return address embosser, could you tell me how you found the process? I'm considering buying the Horchow one that has been recommended on these boards, but I'd love to know how long it really takes, if it is easy to line up straight, how quickly your hand started to hurt... any tips.
My other option would be to pay an extra $25 or so to get the addresses printed on the envelopes, but I think embossed looks better.
