Mums new jigsaw

I bought my Mum another jigsaw as the last one of chocolates she gave back to me as too difficult (It was suppose to be hard but it took months to complete) so this one she couldn't get the edge to fit (she missed two edges and left them in the box that was the only reason).
So Lewis took me to my Mums after work tonight, and the three of us sorted out the edges then tried to find all the dog edge pieces to work from, it seems a plan. Lewis stopped after about half an hour and Mum and I sat chatting.... oops forgot to keep on with the puzzle!
