The plan was found here (I'll be sure to update link once Derrick gives it to me). One creative use for some of the leftover cardboard boxes from some of the online gift shopping we did was to make templates. Derrick measured out the templates into the cardboard, but those out, and used those when marking out the wood cuts. Now he has them ready to go to make more in the future (which are already planned).
And here they are in action!

A few days after Christmas, I received an email from my mother-in-law with pictures of the feeder in their landscape. She said they already had birds visiting!
