Here is an excerpt from the Prima blog:
Complete a layout or other project based on this sketch and enter it here: Prima's Contest Gallery (please write Build-A-Page, May in the title).
On the 25th of May we will choose a winner from amongst the entries to receive a Prima Paper Pack of their choice! Although everyone is welcome to play along, paper packs can only be awarded to US and Canada addresses at this time.
Here is a link to the blog Joy in a Jar where there is a cool tutorial on how to make a double pocket card. You should check it out.
