I CASEd this card from a lady on the Christian PaperCrafts board... and it turns out that she got the idea from Split Coast Stampers and there's a tutorial right there! I didn't use the tutorial, I figured out how to make it from her photo, but the basic design of mine came out pretty much the same as the original except I glued the sides of my flowerpot pocket, and I left the back of the pot sticking up to give the tag and flowers more support, because they seemed a bit heavy. You can see the tutorial HERE. I can't link to Anita's version because the board is members-only so nobody can see it, but hers looks pretty much the same as mine only with a tag on it.
I cut the flowerpot by hand. Fold a sheet of cardstock lengthways instead of the way you fold a regular card, and then cut it in half. Fold the top inch or so down to make the flap, and use a border punch on the top edge. Unfold it again, and trim a very small edge to make the flowerpot pot-shaped. Slide a card-front into the card and measure the edges, then trim it off so that it will fit into the pocket.
Wrap a ribbon around the flap and tie it off in a bow or a knot. Use a gluedot in the center of the flap so that the ribbon can't slide off the card. If you want to add a charm or a punched tag, make sure that you put it on BEFORE you knot the ribbon! Glue the top edges of the pocket to hold the card together.
Alternatively, wrap the ribbon around the entire card and tie it off. People will 'open' the card by sliding the ribbon off.
Punch or cut your flowers and leaves and glue them so that they fit into the pot without the backing card showing through. (Put glue on the bottom half of the top flower/s, and the top half of the bottom ones! Leave the other half unglued so that the bottoms of the flowers hang over the edge of the pot like a real plant.)
I cut my flowers with the Cricut and the 'Make The Cut' software - the flowers came from their free online gallery... but you could use any large hand punch, or any flower shape. The Don Juan cartridge that came with my Cricut has a flower that would work just as well. They're cut from plain cream cardstock and chalked for a more delicate colouring than ink or markers...
