Here is the sketch for the June challenge @ My Favorite Things stamps:
Since I just received the Halloween stamps I purchased from the MFT retirement sale, I decided to use one of those sets for this card:
I used the MFT peek-a-boo window die for the rectangle cut openings, and then added the characters so it would look like they were looking out the windows. The stamped images were colored with Copics and a little bit of Wink of Stella for some shimmer. The sentiment and characters are from the MFT Frightful Friends stamp set, which is 50% off during the sale. Love these characters - just a little spooky but mostly cute, so they will be great for kids' Halloween cards.
