Mine is pitiful and I have an art background!!!
When auditioning fabrics, I take the bolt off of the shelf, try to find a window with natural light and check it out there... What looks fine to my eye in a vertical position or under those fluorescent lights, is totally different "up close and personal". And trying to match a color?? ... a rose by any other name... even with the "dots" on the selvage of a focus fabric...YIKES!
Also... for color comobs, I pour over tons of magazines, in the library, or those given to our guild, or others' quilt color-combos as well as the covers of patterns, tho' I have only bought 1 or 2 quilt patterns in my lifetime! There's so many freebies out there.
Quilt Police? oh, they're real, but I do not associate with them or let them come anywhere near me! LOL
