I have Directv and the only quilting shows I get are the ones on our local PBS - and they come and go in spurts. Quilt in a Day, Sewing with Nancy & the Fons & Porter show - I'm forgetting the name of that one - all come on for me. Quilt in a Day comes on Wednesdays but the rest are on Saturdays.
Just search for quilt then quilting, sewing, etc and you'll find them... but if they don't come up, check again a little later as sometimes they are just not on for some reason... they go away for a few weeks then they're back. Go figure.
