I am constantly buying yarn and necessary materials there. The proximity to the fabric store adds convenience to the quest for the right ingredients. Sellers will always show and tell you everything, give you a look and a touch)
An incompetent (in some way) seller incorrectly picked up too thick fishing line and beads with a small diameter. The prices are generally adequate.
My advice, based on personal experience, if you are a beginner and want to buy something for needlework, do not count on the seller's help.
