On the paper doll cart - PG58 - is a big top. If you use the polka dot paper for the top & sides, a solid color for the inside and contrasting solid color for the frill & flags - you have a very cool journal box. Not sure if you would need another layer or not, but you could always put it on a sky blue rectangle if necessary.
Then use the the same colors to make photo mats. Use the umbrella & pin (juggling) (with the ribbon) as the extra accent pieces on them.
That's a great idea!
