We all need birthday card, so why not create a few so you never run out.
I've used a wonderful Prima stamp - Natalie, coloring her with Copic Markers before fussy cutting.
I created a legal sized card from Bazzill cardstock, then cut assorted Graphic 45 papers.
The birthday sentiment is from Kaisercraft - Hip Hip stamp set. I cut into a pennant shape and added it under the image.
