Unibind Photobook Creator put out a challenge on Facebook back in early June. I entered and received 4 of the window cut-outs from their albums. I should have taken a before picture of the cut-outs but I didn't think of it til now. I received a large rectangle in black, a smaller rectangle in black and and a silver rectangle These were the ones I used in the cat picture.
The fourth cut-out was a blue circle and is white on the back. I made a id tag for my scrap bag. (I used my favorite current paper line - MME Stella and Rose Hattie collection) I plan on putting my info on the white side.
