Then I took some nails with large heads (I wanted them to match the feel of the wood). And nailed it all together. (if I do this again I will run a bead of wood glue to help it all stay together)
I had some old egg cartons and decided to use the top portions to plant my grass. I measured how many cartons would I need to fill my large barn wood box. It was 2 complete tops and then 2 half tops. I cut a top in half and then “slide them together to get the length I wanted and then taped them together so I would have sides all around.
I then used 6 cups of potting soil and 1 cup of Rye grass seed. (the nice man at the Co-Op gave it to me for free because I needed so little and because it is late in the season to plant rye grass outside). It will do great inside though.
I needed something for the cartons to sit on in the box to get them closer to the top. I rolled up newspaper and kept adding until I got the height I needed. I then put small white garbage bag over the newspaper and up the sides a little. (sorry I forgot to take a picture)
I then nestled my cartons into the box and made sure the garbage bag and the tops of the cartons were at the same height. This should help water proof the box.
