I am like you, quilterj. I find it very hard to coordinate fabrics online, because color, print size and what not aren't represented accurately all the time, like when I look at photos of my quilts, sometimes I wonder about they way the colors show.
With that being said, there are a lot of bargains to be had online, and I do buy fabrics just because I like how they look, like the color family, the print or whatever. Many times, I find a piece or two that would work great together in a quilt, but most of the time, I take the fabric/s I want to use to the store and buy more to make the quilt.
Of course you can always buy fabrics from the same collection and these are made to match, but this is not necessarily my style. :lol: I don't like a "designer" to tell me which fabrics go together. I am weird like that I guess. :lol: :XD:
