Here is the wood that we gathered. It doesn’t look like much! It was mostly 2x4s with a few 2x8s thrown in. Just enough to put this mini greenhouse DIY project together.
My husband started by measuring the size of the window and made some simple frames by cutting the wood down to size and screwing it together. We made two 2×4 frames and one 2×8 frame because of the wood we had.
