Party favors - fleece scarves with fringe I made from three yards of inexpensive blue polka dot fleece along with blue rock candy.
Water bottle labels - with Frozen characters and saying "Happy Birthday Ella"
Frozen themed ice skates - Used white skates from Play it Again Sports that I painted with turquoise metallic paint
Cupcakes - cupcakes from a box mix (using an awesome extender recipe I have to make the number I needed) with two tone frosting, silver sprinkles, and frozen toppers. I was pretty proud that I successfully accomplished the two-tone swirl.
Snowflake string cheese - we served granola bars and string cheese for snacks and to make them a bit more snazzy I took out my sharpies and made snowman. One 10 year old sibling declared them "cool."
Birthday girl - although I bought the cute ice blue skater dress on sale at Macy's, I did purchase an Elsa and Anne applique to make it more "Frozen." Miles just wanted to "look like daddy" in his tie shirt.
Tablescape - All laid out at the party. I had some fabric left over from making Ella's Elsa costume for Halloween and purchased more of the blue on sale at Vogue ($2.99 a yard!). The six was just a cheap wood one from Michael's that I painted, and the blue basket and sparkly sign were finds on the same Michael's run that were on deep clearance.
Frankly the most important part was that everyone had a blast - kids, siblings, and parents had a wonderful time. I even got on skates for the first time in 17 or so years (for about five minutes!).
