13 Month Calendar

I'm thinking about making a calendar using bar code dingbats. Each month has to do with products we buy and use as consumers everyday and where they come from.
From nature to consumer:
1. cow to milk2. hen to eggs
3. tree to toilet paper
4. animal to meat
5. grapes to wine
6. wheat to bread
7. cotton to shirt
8. cocoa bean to chocolate
9. bee to honey
10. bone to jello
11. orange to juice
12. tomato to ketchup
13. brain to book

still thinking of some more examples
