As others have said, Cesario is so cute! What a great idea for detachable pattern weights. My patterns weights are glass tea light candle holders. They aren't too wide but are thick and and the perfect weight so work very well. They are heart shaped and a pleasant surprise is that the point end works very well in narrow areas on patterns. I keep them in a basket with a handle so are easy to grab and move around.
Congrats on making your tiny space work so well! You are a master organizer!
