These Indulgence semi dies from Tonic are lovely! I took a regular 6 by 6 inch card blank and scored each side in half to create this card with a centre pop out area that will still fold flat for posting. The centre pop out was a separate 6x6 piece, scored and diecut. There is an inner pop up as well, so it is quite a dimentional card.
If you'd like to see what the card looks like when it is folded for posting, pop over to Blog Tonic for a little more detail.
