3 days before shop
-use store brand graham crackers. They are sturdier, bigger, and square. Winco's Flavorite is good. Honey Maid crackers are not good for houses. Crumble easily and are not square?and they get smaller every year.
2 days before make houses
-to cut shapes from crackers, put rack over boiling water to steam them. Put a lid over crackers. Takes just a few seconds to soften.
1 day before make frosting
-On my first batch doubled this. It made 18 one-third cup baggies. I zip tied the baggies. Then I made one more batch. This was plenty for about 25+ houses.
2008-made 3 batches for 27 houses. 2 batches would have been enough.
2009- Moms created bigger houses so I need 3 batches of frosting for 15 kids. I used 5 boxes of graham crackers. If all moms came to create houses I probably would have needed 1-2 more boxes of crackers.
