I cased this card from today's Queen Roberta's So Sweet card. I love those polka dots!!
The little polka dots are a background stamp by Outlines Rubber Stamps, who are now unfortunately closed.
The big polka dots, I just stamped individually (you can tell by how uneven they are) using a dot from Stampendous' Geo Shapes stamp set.
The moon and cobwebs is by Victorian Greetings, the rubber stamp branch of Victorian Trading Company. It looks like this particular stamp is no longer available.
