Community projects are an amazing way to bring people together.  Whether the purpose is to educate, to own a space or build your community you can be assured that your participants will have enormous fun.   I have enjoyed co-ordinating large and small projects in Hampshire and North Wales.  These range from massive 3D wall art created with tiles made by 500 people, to a small panel created by 12 children with extra needs.  It is wonderful to be part of something that will last for several generations.
