I have ordered teeny tiny cards and stickers from Prinstagram in the past, so when they said they made proper cards for sending in the mail, old school, with a stamp and writing, I needed some! You can print a different Instagram picture (from your account) on each, so I decided to make a mix of regular cards and Christmas cards.
You just choose from your Instagram stash, which is a dilemma in itself. Which to use?!
I printed a few of Bodhi on his skateboard so that he has birthday thank-you cards. Yes, I make my kids send out thank you cards for presents received, and it helps if the card has one of your own photos on it I think.
The cards arrived today and they are fab! If you are expecting a Christmas or a thank you card from me, you may need to prise it await from me, I like all of the cards so much!
Do you send real cards made from paper with a stamp? Or do you prefer cyber cards?

These are great! Maybe I should do the same. It would save time not having to take a picture.
I love them, great quality paper and little brown envelopes. I also love that all of them can be different pictures. My Christmas cards are Instagrams from last winter.
