Here's a basic card pattern that makes a nice thank you card, but you could adapt it with three designs and one sentiment for any occasion. The hearts and flower designs on this card were cut out of a scrap of pattern paper that was made up of circle type designs already.
Background circles - 3 @ 1.25"
Design circles - 3 @ 1"
Background square - email@example.com"
Top square - 1 @ 1"
Start by stamping the dot border and sentiment on a larger piece of paper. Cut around the stamped image to create a 1" square with an even border on all four sides. Ink the edges of all pieces, including background papers. Adhere background papers to base. For 'tied' ribbon - cut a 2" piece of ribbon and loosely tie it around one of the background ribbons for a less bulky knot. Adhere both ribbons onto seam of background papers and trim to fit base. Adhere background circles and background square. Use dimensional adhesive to attach smaller circles and sentiment to the top of the card.
