I made an adjusted top hat with the free tutorial from splitcoaststampers. The original template is smaller but i printed it out 200% onto A3 paper. It was not a complete fit so I had to adjust it a bit.
I used grunge paper so i wasn't afraid it was going to tear during the process.
I finished 50 birth cards when my nephew was born. I used Marianne design stamps and colored it in with normal color pencils. The backgrounds are from Graphic45 and the ribbons came from the market in Nieuwegein.
