is the subject of my demo for the Ashtead Club on Wednesday. These Christmas cards are very easy to make, but look really effective. Change the paper to something non-festive to create a birthday card.
Take nine 2 inch circles cut from one-sided Christmas patterned paper, fold in half - but don't crease all the way across, just pinch the edges. Do the same again, folding the opposite way. You should now have 4 small creases on each quarter of the circle (easily seen from the white side). Make 4 straight folds between each small crease - folding towards the patterned side - thus creating a square.
Different sized cards can be accommodated by changing the number of circles used, such as 4 circles for a small square, or 6 circles for an A6 card.
When mounted onto a card, the white edges form a pleasing pattern. Add glitter, card candy, or anything else that rings your Christmas bell!
