Week 3 and here is my next letter - 'a'. I developed it from a knot in the wood of the lid - making a 'mirror' image to create a round shape, then 'cloning' the gaps in the wood and rotating the image until I made a convincing 'a'.
I have added a couple more letters to my list today. The group is sharing images of letter creations on ALaW2010 blogsite. It's great to see so many varied approaches.
