Here is a card I made using a design from the SCS site. It's called a T-slide card and they are really easy and fun to make. This one was made using a Hobby Habit design from the Rock Hard Fairies range and the DP is from my stash.
This is the card when it is open.
This is one of the other ones that I have made. Very much the same.
They are so much fun to make :)
And open again
