I made these cards for a swap I did with friends last month. Top left is a never-ending card, top right is a 5.5x5.5 square card with a tag bookmark, and the bottom card is a gatefold card.
The insides are all decorated with images I cut from the 8x8 pad. The larger image on the never-ending card is from one of the 12x12 papers. http://www.scraptherapy.com.au/proddetail.php?prod=4500343
