Lost hand-knit colorful winter scarf with blue, red, and yellow stripes in downtown Potsdam.

I lost my favorite colorful winter scarf while walking around downtown Potsdam. I remember having it on when I stepped into a café for some hot cocoa, but I can't find it anywhere since then. It's a hand-knit scarf with blue, red, and yellow stripes, and it has sentimental value to me. If you happened to find it, please let me know!
