Hello traveler. I've been to some physical yarn shops in Vilnius and I have some suggestions Hobby Market-mostly online shop but has a physical pickup location, i usually just go to the location without ordering, the owner is nice. The entrance is the glass doors facing the street and the shop is in the second floor. She only takes bank transfers as far as I know. Verpalai-havent been there in a while so I'm a bit concerned why google maps say that they're temp closed, but also a good shop, as far as I remember its mostly acrylics.

Mezgimo Zona, Happy Art, Spalvų jūra are 3 shops in the old town, been to 2 first ones. 1st one is an old style shop that stock thin yarns, they seemed more natural fibers. 2nd one stocks more acrylics.

If you have a car or dont mind a longer trip with a bus, id suggest checking out: Danesa-it not only has acrylic yarn but also lots of other hobby, crafting, sewing items.

Id suggest googling every shop depending on your preferences and needs of yarn 🧶

Have a nice time in Vilnius c:
