In the 30 years I have been quilting my taste has changed at least 4 or 5 times. Fabrics I bought when I first started out would not even be any where near my stash now. That is why I keep my stash rather small. Why buy some thing today I might not like next week. But when I do see a fabric that wow's me I get at least 3-5 yards of it. And black and white on white I buy by the bolt.
Unlike some others my taste right now is simple. I am so into Amish patterns right now I just love them. I am sure it will change again, and again. I have so much to look forward to, that is why quilting is so great, we have so many styles, patterns, types, sizes, fabrics to choose from to work our craft on.
