My favorites are:
Quiltique in Henderson
www.quiltique.com/ is the largest with the most fabrics, lots of modern prints & is a Bernina & Gammell longarm dealer.
Fabric Boutique
www.fabricboutique.com/ is very friendly and has a good selection also.
Christmas Goose
www.christmasgoose.com/ has a lot of quilts on the wall, it's a small shop with more traditional designs & fabrics. The daughter of the owner (Andrea) is a sweetheart and the son is actually or pest control guy...strictly coincidence.
Fiddlesticks
www.fiddlesticksquilts.com/ in Boulder City is a very cute but small shop in Boulder City, which is also very quaint & overlooking the lake (non gambling town).
