I have been designing ambigrams for many years, mostly on paper and giving them individually as gifts. Redbubble has provided the opportunity to share them more widely.
Designing ambigrams is a great intellectual workout and the finished products are very satisfying. Ambigrams are absolutely fantastic for objects that are often viewed from different angles. And, if you need an excuse to perform a handstand, they make great t-shirts too. Get your own logo!
Most of my designs are black, white, and grey so that they will work on any colour t-shirt. I have to choose a fixed background colour for the cards and the cases but, if you would like a different colour, write a comment or send a bubblemail and I will upload a different version for you. (Better still, vote to allow customers to select their own background colours for any design).
May your purchase bring much happiness.
