I don't know which shop you went to....but, have you tried Quiltique in Henderson? It's on Stephanie...don't remember the address. You can check them out online....but, they are just wonderful in there. I have seen lots of ladies in there quilting in class.
I visit Vegas usually every year to see me BFF and we go hunting...having a ball the whole time.
There is also a wondrful shop in Boulder...on the square....next to the old movie theatre.
