This picture taken with flash shows the sparkle but the reflection of the flash on the acetate means you can't see the details too well.
This one taken without the flash shows the details better but you can't really see how sparkly it is!
I had fun with this technique, but don't try it if you don't do "messy" because it is a very messy process. Also, that Klear stuff sure does pong! Once it dries it's fine but when you first pour it out it is very stinky. So only try this at home if you can cope with sticky and smelly!
Edited to add: A couple of people have said they have never heard of Klear. It's a floor polish, which is why nobody sensible has heard of it!
