I've been to three on Shaverg's list. The one in Boulder City is on the small side, but so cute and homey. Lots of great stuff.
Quiltique is huge and I swear they have it all. It is also a Bernina dealer so there is that as well. If it is new, they probably have it.
Fabric Boutique is also pretty big and they have gorgeous stuff too. I felt like a butterfly flitting from quilt to quilt. And a whole huge wall of patterns. Paradise, simply paradise.
I planned to go to Nancy's tomorrow, but have other stuff I have to do. Grrr.
There is another one that is brand new. I have not been there ....yet. It's called the Christmas Goose and has a website. It should be easy to find, right off the 215.
They also do a Quilt Shop Hop in Vegas. Sounds like it would be fun. And cost a lot of money. It comes up if you search for Las Vegas Quilt shops. I think they pick you up right a your hotel. But I would have to do more then look and that would get me in big trouble.
