I know the pictures are really bad, it's because of the overhead lighting in our kitchen :/
I used some air-drying coloured kid's clay where I found really cheaply in a supermarket! It dries in a sort of hard-foam texture :)
all of these photos were taken before I put the the ring back on
AND..... (tries to think if she's forgotten anything!)
oh yes! I saw this at http://www.meow-box.co.uk/products/chocolate-cake-with-sauce-ring
but didn't want to pay £13 for it!! (2nd Picture)
Start off with a dark brown piece of clay/ fimo.
Divide it into two.
(even though i'm pretty sure you know how to do this!)
Shape your brown clay stuff into a square shape and flatten it, do this woth the other half too.
You want them roughly the same size!
Next, get your white clay
Shape this bit into a thin square and flatten, you want it the same size as the other two pieces.
Now put all 3 squares together!
Get another ball of white clay and squish it to make a sort of squished-ball shape (don't know what to call it!)
Add the caramel over the top with lighter brown clay, then put a ball of red on the top for a cherry, pop it on a ring and voila! you have an AMAZING ring!!
