I do all my actual quilting by hand - it's a strategic move so I have time to save money for the next project before I'm done with the one I'm working on. For example, by the time I'm done with the quilting on the pillows I'm working on, I should have enough saved for the fabric for the quilt top to go with them.
That said, I work at a fabric store where the MOST expensive quilting-type fabric is about 4.99/yd (you might pay 5.99 if it's like a sports team print, but that's mostly for flannels), so I never really shop much elsewhere. I'll go look online, but there's no point going to a quilt shop here in town with those prices, and we have a good enough selection I can always find SOMETHING I like. The most expensive fabric we have is a faux fur type deal at 13.99/yd - even the apholstery and drapery fabric tops out at 8.99/yd! I love my job...
