Here are cards I made for my grandsons for Halloween.
I used the Mini Monsters Cricut cartridge and cut the monsters at 3 1/2". The base of each card measures 5 1/2" x 4 1/4", and the mats are 5" x 3 3/4". I used Recollections cardstock for the bases of the cards, The Paper Studio Spooksville paper pack for the mats and Bazzill cardstock for the monsters. I also added googly eyes, gems by Queen & Co. and Action Wobbles to the monsters. Below are pictures showing the monsters wobbling.
I sure hope my grandsons like their cards.
