How do you put an artistamp or faux postage on mail as to not get in trouble with the post office? Here in the US you can actually make real and useable stamps at a couple of sites (which you would think would take the fun outta artistamps). There ARE restrictions however and with artistamps there are NO restrictions. I get that. I just don't want the postage police at my door. So do you put them anywhere BUT the upper right hand corner, on the address side of mail, where REAL stamps go?
