This is a great pattern for making a special card. It can be embellished as simply or as ornately as you like. These are by Pat and Elly. Keep scrolling down for some good links on how to make this type of card.
Here is a link for a pattern.
Here is a really good you tube video tutorial which shows step-by-step how to do the folding of the card. I like the way she decorated hers. She calls it a "Step ladder card".
Happy card making!
Thanks for the inspiration Elly and Pat.
