At least crafting ones anyway. My favorite tool(s) aside from my Cricut and my ATG are my Spellbinders Dies and Cuttlebug (but only because I couldn’t use my dies without it). I am up to about 14 sets of dies and just bought my first ones within the last 6 months. In the picture below you can see my two books I made to store them in. I’ve gotta get to work on more books because I’ve almost filled both of mine already!
