New Bella! Botanical 12" x 12" Single-Sided Cardstock - #4 Multi Birds. When I saw this I thought these birds would be adorable to cut out and use to make ATCs and other art projects. They are the perfect size to fit on 2 1/2 in. x 3 1/2 in. ATCs. Please note this is a single sided piece of cardstock with white on the back side.
