Audra,
I'm so glad you liked them.
Those are mine.
I got those from
www.goeslitho.com
However, you do have to order in large quanities from them.
Vippes is a good source for smaller amounts, but are more expensive.
Here is the link to these calenders in my gallery. There is a lot of information there from me as well as others about size and ordering info.
Good Luck and thanks again.
