OK, I'm making a slow start today, after an unusually late night yesterday. Here's the answer to the puzzle.I don't actually know the name of the utensil with the holes, but yesterday's pic was sunlight from the window reflected from the shiny metal surface. What I actually photographed was the unpainted plaster wall behind the stove. That's the stove you can just glimpse on the right of the pic. The distortion in the pattern was caused by the curve of the metal.
My textile task yesterday was spinning more silk caps. Either I was having a lucky day or my technique is improving, because I managed to get through a fair bit without breaking the yarn or making my hands hurt. I'll see how I go with it today.
