This was a preprinted panel. I did one last year for a friends daughter and it too was preprinted, it was a toy store and the pockets were toys, really cute too. :)
You should PM jnebug and ask her where she found it, or who makes it. jnebug mailed it to me, I haven't seen any like it our here, haven't seen advent calendar panels anywhere in town since our other fabric shop closed this year.
I would like to say thank you to everyone for all your kind compliments. :)
