I recently posted about a DIY car banner and I used the same idea for our thank you cards. Follow the instructions here to make the below thank you bunting and make these super cute thank you cards for your friends and family.
I bought the plain cards and envelopes as a pack on ebay, you then simply glue the photo to the front of the card. Simples!! Again if you’d like the pdf version email me at firstname.lastname@example.org.
