I painted the canopy stripes black and printed off a front view of Grace's Patisserie which I glued on (and then covered with laminate).
I also added in treats from the Target brand Our Generation Tea Set ($16.99), along with treats from various swaps on AGPlaythings. -- YUMMY!!
The finishing touches are the tiny bags and boxes printed off and assembled using this idea/template from AmericanGirlIdeas.com blog (free).
UPDATE: I made a small platform with wheels out of things I found after dismantling some extra "Build-and-Grow with Lowes" stuff this afternoon. And spray painted red to contrast the cart.
UPDATE 3/4/15:
Didn't find the handle, so ordered one from Lowe's.com and super-glued it to the cart.
Completed Petite Patisserie!
