I know Crochet Dude has some of his patterns at Yarntopia. And he has talked about Yarntopia. LOL thats how I learned about it.
I think Mer has been to Nancy Knits. Maybe we can get a review from her.
Here's what I know about them. Yarns2ewe has tons of sock yarn. Very large selection of just about everything. The ladies who frequent the shop have held my baby while I look around, pay etc.
Yarntopia is a smaller newer shop. VERY friendly, VERY baby friendly. I took my three year old and 8 month old in and spent a relaxing time as they played with books, toys, etc. and I carried the 8 month old around mostly. They also have a changing table in the restroom. I've taken a class there and one of there teachers is a Knitty designer. Real sweet, pretty knowledgeable. Relaxing, sweet people, kinda reminds me of this place. It feels like a family there. I've seen the shop owners handle "situations" in a real sweet way.
Yarn Barn is also wonderful. Its a large shop but also has needlework. So they probably have the same amount of stuff as Yarntopia. They will bend over backwards and at times I've had four different women ask if I need help finding stuff. Even the knitters who are there are so sweet.
What are you shopping for specifically?
