So I just got the new Love Struck Cricut cartridge and I just had to play with it. Nothing to fancy at the moment just playing around with the cartridge. I wanted to see how the mailbox and box came together so I made those first. For each of those I used my 12x12 mat along with the same size sheet of paper and cut them using the Fit to Page feature. Using that setting your Cricut will cut the mailbox at 11 1/2" and the box at 9". Those seem to be perfect sizes to use for you kids Valentine's party and gifts.mailbox
For the card I saw someone else use the couple heart and I really wanted to play with that so this is a quick and cute card I came up with. I just love all the details in the hart. Because of all that detail I would not make the hart to small. I cut one out at 2 1/4" and one at 3". For the card I choose the 3" heart. The word "love" is also from the cartridge and I cut that at 1 3/4". These sizes seemed to work out well with your standard size card.
