When I attended one of my groups within the past month or so we coloured in bits of paper with patterns on and I took an extra one to make another card at home.
I used pastel coloured pencils to colour this one in and then simply glued it to the card. The card I used is from a pack I specifically bought that were that size.
I hope you like it as much as I do, I made this card for my mother-in-law on her birthday.
