Wow, CodeBorg. Sliders, ropes. Cool.
This is teeny, but I'm looking forward to it. My old (1900) house has been renovated a few times, and there is a big window in the kitchen that used to be an outside window, but there was an addition, covering stairs going down to the basement instead of one of those flat "there's a tornado coming!" cellar doors. So there is a big hole, no glass or anything, about 20 inches off the ground, and quickly descending stairs on the other side. Since my kid's a little monkey, we have a safety gate filling up the bottom part so she won't climb up there and fall.
The safety gate is atrocious -- gray plastic, bulky, yucky. It's such a nice, light-filled window, and then... blech.
SO -- I had an idea. I'm going to build a rail (dowels and 1 X 2's), possibly with a ledge/ shelf on top. Then I'm going to custom-make some simple rectangular planters at my pottery class to fit the space. (Thought of one long planter, but don't know if it will fit in the kiln.) The rail will be at the inner edge, leaving about 6 inches on the other (outside window) side. So put the planter(s) there, and plant climbing vines -- probably sweet peas. Can also use it for a kitchen herbal garden or any number of things.
Would be SUCH an improvement.
