It is one of my favorite sites to go when I am looking to find something in particular, especially when it comes to knitting supplies.
The filters are very helpful as well! Sometimes typing out long titles can be difficult with so many different threads. Not much to dislike about this website other than that it could use some improvements like adding more categories or having easier searching options available. If you have any questions regarding yarns, patterns, etc., then this is an excellent source for finding everything you need at once.
