I think DaveMac had a good point with "material collecting". That certainly described me the first several years. At first it was quite broad. Acquiring a little of everything in common or basic colors at first, then expanding the colors and adding more obscure materials. I don't think I'm alone in saying I have packages of some materials that have never been used. Now I buy stuff that's new that 'might' be useful, or new items just to tie a specific pattern. For some of us, collection materials could be be considered hoarding. Glad I'm not one of those types!
