I think the idea would be easy to adapt for any holiday or birthday- you might give it a whirl if you're looking for easy card alternatives.
And one more happy thing-  My 2013 valentine's block from my mom!  She's making us (my sister and me) one every year, and someday we'll put them into a quilt.  This years features gradients (from photoshop) and embroideries from her embroidery machine.  So fun since both of those are things she's been working with a lot lately.
