Home decoration is a creative work, it’s about improvement, freshness and beauty in your home environment and although painting and decorating is a part of the building trade it also borders on art in some projects, you are building and you are creating and it’s very satisfying to see the end result when it works out well which it can if you have the right attitude. See your paints, fillers, stains and papers/wallcoverings as your mediums and think out your projects on paper.
