This week I've up cycled a cotton bud container. I've used air dry clay in the moulds as this is more pliable to work with on curved surfaces. Its taken me a fair amount of time and practice to use air dry clay in moulds and initially I had many failures because I hadn't realised my clay was too wet. It's important that your clay is not to sticky or too wet or too dry. I find there is a difference in the moisture levels of different brands of clay. I find a good rule of thumb is if it's sticky just leave it to one side to dry out a little before you use it. It's also important to remember to keep any clay you are not using in a sealed container, I roll the top of my packaging back over and tape it all down to within an inch of its life just to make sure.
