Lego and k'nex construction

My living room is the centre of creativity today. Many Lego sets have been built and k'nex has been reconstructed.
Since our visitors have gone we've unpacked from our trip away and tidied up the house a bit. I had intended to take down xmas decorations but somehow that didn't happen.
Now we've eaten more cheese, more cake, more chocolate, the fire is lit and candles are burning. All I need is for two boys to go to bed so I can enjoy a quiet relax after the busy past few days :-)
