Crochet, Dice and a mystery object

 I bought 11 balls of yarn from a nice little shop in Cavendish Court.... and crocheted a little strip and numbered them all from 2 to 12.  And then threw the two dice.... and this is what I have done so far.... two rows of each colour then throw the dice again..... until it fits a double bed (!) There's quite a way to go still.

 And what on earth is this.....

... you'll have to wait and see - I have sanded it down and will be painting it with sealer in the not too distant future - I think I shall give it one coat before I put it together then one or even two more once it is built.  I can't leave it like this for too long because it is taking up half of the kitchen floor.
