These are the invitations that we made. I just used some pretty scrapbooking paper in the colors that she liked. I traced around a large lid for circles that I cut in two for the icing, traced around a coke bottle top for the "cherry", and used the hole punch on some trimmings from the scrapbook paper for the sprinkles. We then drew a number seven with a glue stick and added glitter. The party information was on the back.
Hobby Lobby's Christmas ribbon includes lots of colors besides green and red. Check it when they have their after-Christmas markdown and stock up on colors for the year. That's where I got the pink ribbon I added to the back of the chairs.
I found cupcake stickers that I added to plain bags and wrote their names on each one. I added another sticker to each napkin. Snacks were served in mini cupcake wrappers. Also at Hobby Lobby, I picked up these little wooden cupcake ornaments that were in their Valentines Day merchandise for the girls to decorate. I also found kits to make your own candy necklaces.
Here is one of the brooches we made for each girl. She got to design each one. We used large and small cupcake wrappers, old buttons and trim.
