My favorite things in my LQS
Lots of projects/samples on the wall and classes for them.
I love the way my LQS has fat quarters cut for almost every bolt of fabric. They have a narrow shelf above each stack of bolts and it is so convenient to be able to pick up a fat quarter and not wait to have them cut. (Especially when you have a hubby waiting in the car, lol.)
I like to have help picking out fabric for a quilting project without seeming like I am a bother. Anyone can go to Joann's/Hancocks, etc but it is nice to have that individual attention when paying the higher prices.
The block of the month clubs are fun. Also, Jelly roll club where they make different projects, UFO days where you can sew for a day....Some LQS's have one night a month where they sew charity quilts (Project Linus, etc).
I like to be able to pick up that special ruler or tool I can't get at the chain stores.
Friendly staff.
