If you would like to obtain some Tibees merch, I have a couple of designs available.
One is the mathematical forest chalkboard design inspired by square roots, cube roots, logs and trigonometric waves. I made this artwork myself and it is available at Teespring.
I also have an older design, the Klein Bottle kitty, available on Crowdmade.
I enjoy making handmade felt characters and give them out as a signup gift to my $50 tier Patrons. If you want one you can choose the design and color.
