here's my card...
it fits in a business sized envelope so that should give you an idea about the size.
Chatterbox pp- (new Chalet)
May Arts ribbon
"merry and bright" rubber stamp
colorbox silver ink
metal snow flakes (look familiar Em?)
The dark blue "card" is mounted on the lighter blue card stock (a tip I picked up at an SU demo)
TFL- hope you love it neighbors!
