Free Theme Postcard #2

Can our own photos be used to create this?

Thank you for asking. In this case if it is one photo I would say no, only because most of the swappers attracted to these swaps are hands on art/crafty souls (not sure if that's an ideal description) who like to receive similar in return. If it was a non digital collage of photo pieces it would be OK.
I had been thinking of a "one picture handmade PC swap" ( I've taken part in one before) where you use one picture ...either a photo or a found image from a magazine or elsewhere with no alterations. I will set one up and see what interest there is.

What if it's a "chunky" postcard and would have trouble going through the mail system?

Chunky is not the best way to go with naked postcards as the postal machinery can make a nasty mess with them. If you mean thicker card cutouts glued on, some people cover the picture side with clear tape but that won't work with more lumpy/bumpy add ons. I will say that sometimes I have seen quite chunky cards make it through the mail but it is a risk. You can always ask your partner if they would be happy for a card to be sent in an envelope. I know that is not part of the swap requirements but a private agreement is always a possibility. Bear in mind that your partner may not want that as it is after all a naked swap.
