Vintage Diner Birthday Cake

Last weekend I went to my Grandpa's 80th birthday party.  We did a vintage diner theme.  It turned out so cute.  I forgot my camera at the party which was a bummer. However, I made the birthday cake and took a snap of it before I took it to the party.  I colored white fondant with Wilton's Food Coloring Gel.  You can get it at any craft store and most Walmarts.  The circles were cut with various cookie cutters.  Sorry there was no tutorial with it.  I'm not a professional cake decorator but I think it turned out cute for my first cake.
