I made two of this "accordion fold".  This dsp was a fun when to use for this type of card.  Two of our grandchildren will be getting these.

The paper I used measured 12" x 3".  It is scored at 3, 4, 5, 6, 7,8 and 9.  The 3" sections on each end get glued down.  For full directions, you can do a search on YouTube for "accordion card".

Thank you for coming by today!
