The small printed dates are the expiration dates of our milk bottles.
The dotted white painted lines in-between the stitching mark how many bottles of milk were purchased that day. If we bought one bottle there's white below the day. If we bought a second bottle, there's white to the left of the day, and if we bought three, there's white to the right of the day.
The dotted lines connect the date we purchased the milk with the expiration date.
The solid white squares in the Sunday, Tuesday and Thursday columns show the expiration days of the milk company we commonly buy our milk from.
The dotted lines not only help to explain this project, but design-wise, the gridded "calendar" is now an abstract design because this is an art piece, not just a research project.
Check back for more updates through the end of the year. I am looking forward to adding more dates and dots as we need more milk.
I also have some ideas for a topic of my 2018 Dates in a Life Project, and will announce it in late December when confirmed.
