I usually buy from a line of fabric if I shop online so I know all the fabric will match. One bad thing about that is that a lot of the times they only have 2 or 3 bolts left of the fabric line, so I have to look around at different online stores to find more of the fabric. But I find lots more selection online and they seem to have the latest fabric before any LQS around here gets it. I seldom buy one piece of fabric unless I know for sure what it is, like what fabric line it's from. I've been disappointed in the fabric when I buy without knowing the exact fabric before hand. Usually it doesn't look like the picture quite enough.
