This awesome fun fold card, called a Diamond Fold, has been a favorite of mine since the first time I tried it. The images in the Country Flowers stamp set are sized perfectly to fit it!
This is the base for the Diamond Fold Card. I used Misty Moonlight
cardstock. To create the point, make a small pencil mark at 2-1/8" and
use your trimmer to cut from that mark to each end of the scoreline, as
shown in the photo.
Here are the rest of the measurements for this card:
3" square of Misty Moonlight cardstock
2-13/16" square of Basic White
2-5/8" square of Country Lace Designer Paper (Smoky Slate)
2-7/8" x 4" Basic White for inside
3-1/8" x 4" Misty Moonlight Designer Paper for card front
2-1/4" x 4" Misty Moonlight Designer Paper for inside (to the right of the
Basic White)
3-1/8" x 4" Smoky Slate Designer Paper for inside (to the left side of the
center fold)
