I keep my designs by digitizer or website. Those I have purchased will be in a folder by set or if individual in a singles folder with a "$" on it so I know they were not freebies. I also have a folder within my "Designs" called Projects for those I'm working on but not yet finished so I can go back to those designs easily. Also in the "Projects" folder I have a folder called "Labels" as I embroider all my quilt labels and have made a basic triangle design to set the lettering within. I use Embird for all my designs when I go to slice and dice, change colors, combine or make my labels and convert.
