I saw this "paper quilting" technique used quite a while ago by someone on the Studio Calico design team, if I remember correctly. I was absolutely intrigued by this method and went on the search of something easy to replicate for this layout for the Blue Moon Blog. While the technique is not difficult, it is very tedious - I will just warn you now! But the end result is very lovely :-)
I also used some of the new Crate Paper "Paper Hearts" line. I really love the non traditional shades of blue in this Valentine's collection! And I am still loving those little doilies by Jenni Bowlin!
