I have been having a blast looking at what seems like zillions of designs that for lack of better classification I call quilt blocks. I see tons of uses for them, but I am just one person.
These designs are in the process of having final color selections placed on them. When I digitize, I usually select a color scheme that I want to work with for the day, but that doesn't mean that the designs will be grouped together. I pick what catches my eye for groupings with mostly no reason.
