All the cards I've received in swaps

For a card making group that I'm on, I'm suppose to post what I've received. I belong to two different groups. One group, everyone I've swap with tends to put post-it notes in the card saying who it's from. Unfortunately the group that wants these photos, no one does that and I don't keep the used envelopes with the card once I've posted that I've gotten it (I'm trying to keep the clutter down to a minimum). So, I'm just going to scan them all and let everyone enjoy everyone's creativity.
