West Houston is fairly vague because it is so HUGE here but LQS that come to mind are Quilters Crossing in TomBall, Its a Stitch in Humble, Quilt N Sew in Katy, Quilt Works in Cypress--that is all that comes to my mind right now but its still early and I am sure there will be others that have more.
I agree with Irishgal--tisk tisk for not coming along we could have had a good time:-)
