Protect and improve your KeepCup
I bought a "Keep cup" as a Christmas present for my sister. I was worried that the "cup" might not "keep" for as long as intended because the base of the glass was unprotected. Then I had a lightbulb moment. Sugru to the rescue! I made a long sausage from black sugru to protect the base and lower end of the cup and just wrapped it around the bottom of the cup. Bob's your uncle! A Keep cup with a protective sugru base, which matches the colour of the lid.
