I"m pretty much like Annette. I like quality fabric that (hopefully doesn't fray too much) and good thread that makes me and my machine happy. I'm more picky about grain when I'm making garments. With quilts I've found it's not as important.
Placement is a big deal with garments. I once followed a lady down the street and was very amused. She was wearing a dress with large red flowers on it. Two of them were placed right on her rear end and "walked" when she did. I've learned to watch for that when I'm sewing and to always check the rear view when I buy stuff.
