Good marbles are hard to find - I bought these in a second-hand charity shop. I think they are fairly old... what I like about them is that they don't have the swirly bit in the middle, which makes them more interesting somehow
A great shot. I love the colours, the patterns of the cloth and that the upper part of the photo is blurry - that steers the eyes to the marbles. And the reflection inside the marbles is quite interesting too - you had an invisibility cloak, didn't you? Just admit it .
