TG, if you mail with a priority envelope, I think a tracking number comes with it. That's a good reminder to send your partner the tracking number when you mail, so they can watch for it and will know where it is.
Embroidery for me is a no. I just don't like it. I do love hand embroidery, tho. I am probably the only one in both groups who doesn't like machine embroidery, so please forgive me, those of you with multi-thousand dollar embroidery machines! :P
