So... here they are...
So, start by mixing your favourite colour polymer clay (PC) with some white. In the past I have found that if you do not mix it with white then it cracks and loses definition when you bake it. Perhaps that's just that brand I use??? Anyway, I always mix my coloured PC with white. It's pretty tough to start off with, so it'll take some time to make it malleable. When I'm making multiple finger pint discs I start off with a large ball of PC and divide into even portions so that all the discs are the same colour.
Once you've completely mixed the colours together divide evenly into the number of discs you need and roll them into balls.
Now place the balls in between 2 layers of baking paper and use a book to press flat. Using the baking paper and book make sure the disc is even and smooth with none of your fingerprints all over it.
Next step is to get your little one's finger and firmly press it into the PC disc. You will need to use a bit of pressure as the PC is still quite firm.
Now get out you cuff link bases and hot glue gun.
I found the best way was to glue directly onto the back of the disc and then quickly attach it to the cuff link base.
Such a cute little gift. Yes the etching is a little rustic but hey... I think they're cute. :)
