Amassing another Unused Catalog

I seem to be amassing a large catalog of individual flowers, painted in watercolor from my inspiration photos.  Alisa Burke (in Watercolor Blooms) suggested we play with our supplies by doing this.  One of the objectives was to really test out all the things that our supplies can do.  Mine seems to be evolving into another catalog.  (Obviously I like to sort and name things.)  Unfortunately, when I go to paint I don't seem to refer back to these.  Maybe that wasn't the point; I'll have to watch the video again.
