Distance really does make a difference in your fabric selections. I line them up in a cart, then walk over an aisle away. When I take that farther look, the ones that do not belong, will pop out at you. They also make a de-magnifying glass that will provide that distance if there is not enough room for a spacial viewing.
Since I now have a portable design wall, I can audition my stash fabrics from across the room. The "stinkers" for this project just might be the "rose" for the next one.
