I was able to repair a sink strainer that wouldn't stay in the open position by taking a piece of plastic tube from a marker, the fatter kind of children's marker, and cutting a slit down the side so I could snap it onto the stem of the sink strainer to hold it up. It would have been easier if I had cut it to the right length before making the slit.
I also experimented with making a simple dust jacket for a book out of quilting fabric. It looks nice on the shelf with the normal books, although the fabric sticks out a bit at the top and bottom of the spine. I expect that it will collect dust and need to be washed and ironed at some point. I perhaps should have pre-shrunk the fabric.
Yesterday I used a handed-down upholstery remnant to replace the seat on a freebie metal patio chair. The chair uses splines in channels at the sides to hold the fabric in place. The original plastic mesh didn't have hems or channels sewn at the sides, but I put them in the replacement, for strength. It took a considerable amount of work to put the new fabric on, with the splines in and with tension across the width. I am sore today, but not nearly as sore as I should be, thanks to milk. I had sore muscles before I started. I'm somewhat doubtful about the strength of the fabric, but it supported an adult's weight, cautiously applied.
During my break I painted new letters on my keyboard. It's not that old, but almost half of the alphabet had disappeared. I used a contrasting color of nail polish to paint the missing letters on--in Morse code. I didn't get all of them on very clearly, but it has helped me learn some more.
