I don't have any Halloween dishes really, but I bought the sheet of decor elements to make my Halloween pumpkins, and then I had lots of pieces left over.
I went to walmart and bought 3 inexpensive white porcelain dishes and applied my Decor elements on them. I just tested them out at my Open House and they have done quite well at holding food and being washed and tried. I am not going to try the dishwasher, but they do well by hand! Yeah!
I could even make place cards and invitations with the coordinating stamp set!
