Yarn shops in Prague

There is on in the Dejvice area just off the main roundabout (Metro stop right there), can't remember the actual street but I did pass by it a few weeks ago, I will try and find it.Might be worth asking on the Ex-pat website.I won't be back in Prague till mid October.

this might help.

There is a yarn shop on Level -2 of the Palladium shopping centre. The name escapes me, but it is on the right as you approach the shopping centre from the Namesti Republiky metro concourse. Very central; you can't miss it.

Hi! I live in Prague and am an experienced knitter. Like you, I check out the yarn stores in every city I visit. (I was in Norway and Sweden over the summer and was in heaven!) I have bad news for you: Prague is not a city where you can go to wonderful yarn stores and browse. There used to be three lovely, small yarn stores here, but they have all closed (they're now online-only). The yarn store in Palladium is fine for cheaper yarns--I use them all the time--but it's not really a place to see pretty, interesting yarn, and they don't have patterns or English-speaking staff that could help you select yarn for a project. The Palladium store looks more like a small fabric store in the US with some yarn at the front. The yarn department on the 4th floor of Kotva is similar: lots of inexpensive yarns and supplies, but nothing all that interesting. I don't recommend the store near the roundabout in Dejvice--the ladies who work there don't let you touch the yarn! It's all kept behind a counter! Sorry to be so disappointing.
