Window box cold frame

a window-based cold frame

My results (on my first attempt) weren't pretty like my gardening friend's, but serviceable.

But I didn't need power tools.

I used nails and twine to secure the sides (so I can take it apart to store), and the top lies securely on the sides.

If I can find two taller end pieces (or the right-sized windows), it would look much nicer, but it seems functional.

I sowed some spinach and arugula seeds, and transplanted some lettuce.  We'll see.

I'm hoping that my second box (in a bed in the mountains) will look nicer, but that depends on matching the windows with the ends!
