One of the fun ideas I found on Pinterest lately is from Putti Prapancha. Sheframes her toddler's scribble art work with various shapes. Red Ted Art suggested that this would be a good format for thank-you cards.
I thought that was a terrific idea; so when my cousin made this sweet dress from a 1940s vintage pattern for little G, we decided to make a dress-shaped frame thank you card.
It seemed to work especially well to line the edges of the frame with colored marker to help define the shape a little better.
Thanks for the good ideas, Red Ted Art and Putti Prapancha!
