Decide what fits your abilities, taste and budget. The kinds of garden art you can create are limitless, but it all begins with ideas and imagination. Before you can start making your art, you have to know what you're going to make. Visit stores, browse online and sketch ideas.
Purchase your materials. Anything under the sun can be used to make garden art, such as wood, glass pieces, rocks, cement, metal, plastic and more. Once you get the main pieces, you have to decide what you are going to transform those into and whether you need materials such as paint, glue and nails.
Put it together. The skill required to assemble your own garden art varies by what you are choosing to do. If you are doing a glass mosaic piece, it will be easy but time consuming. If you are making a wood bench, it will require drawings, plans and trial and error. If you are making a piece of metal artwork that needs to be welded, you will need special welding materials and safety precautions.
