I did purchase the 12" x 12" Collection set that Photo Play has, but I always like to have more cardstockers tickers to have. This is a French theme and having just these stickers can be very pretty to use on all sorts of projects and paper crafts.
I bought the set which includes one sticker sheet but I usually buy a couple extra sheets so I don't have to decide which friend gets the "cute" sticker on her card. I'll have plenty of bicycles, dress forms, and Eiffel Towers to go around. They are very lovely.
