We grabbed some sealer to spray over it once it was painted and some birdseed to fill it with.  He started by painting over the windows, which I had covered in tape, but he was really into it.  After some redirecting, he got the hang of it and was painting the wood.  He started with blue paint but I wandered off to put Nate down for a nap he ended up pouring some pink and white into it and stirring it up.  So it ended up mostly purple.

After many, many coats of varathane I figured it was good enough and we filled it with food and I hung it outside.  Then I had to move it so we could see it from the kitchen window and avoid going out into the freezing cold.  I haven’t seen a bird at it yet but hopefully someone will notice it’s there soon!
