I have my favorites that (at least I think) will never change. For example: my Cricut Expression and all the cartridges, my Gypsy, my paper cutter, my ATG gun and certain other adhesives, my craft mat... You know, all the "must haves" that you can't do without.
Then there are things that I "seasonally like" and gravitate towards. At the moment on my list are...
My (old fashioned) Dymo labeler and clear tape for it.
All sorts of (weird) papers; tissue paper, different packing papers, pages from old books, maps, kraft paper and so on...
Americana acrylic paints (awesome coverage with just one coat)
Tattered Angels glimmer mist
Jute cord and hemp cord.
All recycled stuff
Tearing and distressing
