No cost to have your account QR code on the postcard I make. I wanted to do it so I’m paying for the printing. 👍 If you want to donate sats, that is very kind, but not necessary.

The postcard will look like this - QR codes from several accounts. The purple box will have a QR code for the hashtag #artstr but that gets added by the printing company- this image is a mockup I made to explain my idea.

Since it is just QR codes, there is no choice of file.
