When I first started out doing my specialty art work, you could have seen all my supplies in a small box. (And then I thought I had so much!)
But it seemed then that someone would always ask me if I could do so and so and I would then have to go out and get the necessary items...which then led me to buying things that I thought may be some day would be used to make this character and that character. And next thing I knew, I had to have better and more numerous places to put all my wonderful little goodies , doodads, fabrics, yarns, threads, and a host of other things!
I moved off of the kitchen table to having a whole room to myself and from one cardboard box to 7 or more triple drawer units, and two multi mini drawer units that hand on the wall. (And I confess to needing twice as many as I type this!)
So, yes, I do hoard supplies, of all kinds,and I have an thick notebook that I keep alphabetized ideas in, sketches and the like for when I need direction. It is the best way I know of for any creative person to avoid having a dry spell in their creativity!
My husband says I have enough things to make 400 dolls...he's probably right, but
it doesn't stop me from seeing that perfect little item or fabric that begs to be taken home and added to my "someday I will need this" stash! One can never have too many supplies...right?
