The Haapsalu Shawl Museum tells the story of the town's famous lace shawls, fine enough that the classic boast says one can be pulled through a woman's ring. The displays show patterns, finished pieces, and the craft tradition behind them.
It is a small stop, but a good one if you want something local and handmade rather than another castle or promenade walk. The museum also sits close enough to Haapsalu's old town sights to fold into a slow afternoon.
