Sea jewels

I got quite a cold. At this point I already wear my winter clothes but I went to the beach yesterday, is a long walk to get there and the hot sun was shining, the water was calm and so clean I couldn't resist. It was fresh but it felt nice, in the nordic countries they swim in the icy water and nothing happens to them, unfortunately, I got a little cold when I went out.

I picked up some sea shells with holes that I made into stitch markers,

I don't know if they will be very useful, they seem fragile.
And also a pair of earrings.
