Sizzix & Sidekick die cut machines and dies, stencils, pokey tools, stamp blocks (I use them for everything - stamping of course, flicking paint spatters, palette, mixing texture paste)
I agree, it's my die cutter. I have the Spellbinders Platinum and way too many dies. But, I use them on all my layouts and projects. Also, my chipboard and paints. I have a variety and use on many of layouts.
I love my Empress die cutting machine from Anna Griffin. It uses a magnetic mat so my dies and paper don't slip on the mat. My next favorite tool is my 5" Westcott Non Stick Titanium scissors. Slim and super sharp!
I don't usually buy top-of-the-line craft supplies, but I do have some great products that I've tried and really love. Those are brush pens which great for handwriting, adding color to artwork, journaling and more. Another things are Cardboard paper and scrapbook. Really, just paper in general is a great craft supply, but I use heavier paper like cardboard and scrapbook paper more often. I use scratch paper for everything from making envelopes to using it as a blog photo background. And some things are guillotine; hot glue gun, sharpie oil-based markers.
When it comes to die cutting machines, I only use Sizzix. I love their products, and they have always stood behind them. To me, that says a lot about a company!
I have a pair of Mrs. Grossman tweezers that I love, and cannot scrap without them! Just wished they didn't discontinue them! Other tools would be WRMK, like their trimmer. It reminds me of the old Making Memories trimmer. I wished that brand would come back!!
