Here's what I learned from the project --
Tying slices of dried lemon on thread so that they're evenly spaced is harder than it sounds.
So is hanging them from a window frame with thumbtacks while four different family members wander through the kitchen asking what you're doing and why.
What I couldn't do was get a decent picture. I tried different times of day and different angles, blaming the light. It was later in the week that I figured out what was happening. My wonderful intelligent camera was focusing on the tree and blurring the fruit slices. Once I told it that I was taking a portrait, it focused on the fruit and blurred the branches.
It's not just a matter of making the thing and having it turn out the way you hope it will. Sometimes it's a matter of making the thing and having it look as good in pictures as it does in real life.
