I recently ditched my land line so had to change all the pet's ID tags to my cell phone number, plus my kitty Squid Bean, constantly looses his tag mysteriously in the night, I think the neighborhood is peppered with my old phone number and lots of nice collars. I loved ChrysN's Instrcuctable
on how to make a pet tag so much, but I didn't have a toaster oven.
If you don't yet know about Sugru I will give you a little information here, otherwise move right along to the steps. So, Sugru is a really great new product made in London. It acts like sticky clay for a few minutes, then acts like clay for half hour or so, then it hardens and acts like rubber. In fact it is silicone rubber. The hardest thing about using it it to open the package and think what to do with it - once you do that though the ideas just keep coming. But don't open the package until you know what you want to do.
It bonds to itself, aluminium, steel, ceramics, glass, wood, leather and some plastics. Go to their website to find out how to buy it and for lots of great ideas on what to do with it at Sugru
