Great place to go for wool as the selection is unbelievable. A knitters paradise. This is the kind of place to go to if you know exactly the kind of items you need or want to browse.
romni is definitely the giant of the toronto knitting circle...their store is jammed from floor to ceiling with yarns, supplies, patterns and books. the staff tend to be a bit standoffish, but that is the exception rather than the rule. there are some great bargains to be found for the patient hunter and the vast selection is actually a very inspiring thing in itself.
Romni Wools has the most comprehensive yarn selection in the city! They're packed (quite literally, in places) from floor to ceiling with yarn of all kinds to satisfy your fibre needs.
This store is so big that they even have a separate room for knitting books and patterns on the main floor, and in the basement they have spinning fibre and a room full of yarn that's on sale.
The staff is friendly and helpful at all times. I've never had a bad experience at Romni!
If you are ever looking for wool this place is the place to go. It has many different varieties of wools, from synthetic to natural. They are also very helpful if you have questions about as pattern or about wool.
