I like 3D cards so this is great way to make faces for a Dolly topper. Fimo polymer clay is usually around the £1.50 mark, and I can get around 20 faces from one small block. This makes is a very cheap way to get a really interesting topper for your card. Firstly, you need to pull of a bit and sort of pinch, roll and pull it about in your hands until it warms up and becomes plyable. I have put the three stages on here, rather than take 3 pictures. Then, you need to put it on a flat surface and squash it into a circle. Now for the really technical part. I use an old pen lid half pushed into the bottom of the circle for the smiley mouth. A weeny piece of fimo for the nose and a skewer to poke 2 holes for the eyes. Then you stick it on a baking tray/dish/pyrex and bake it in the oven for 30 minutes at Gas 1/130c. When it comes out it's hard and you can use glue or DS tape to apply to card.
This is the finished face. Up close, it looks a little ropey but that's because it's magnified. On the card it will look perfect.
I will be back tomorrow with making the rest of my Dolly Topper.
