Trial and error
Decided that we would paint our planted tyre green to soften it a bit and create a splash of colour. That worked well until we tried to use a stencil to paint white lettering over the top. Unfortunately, the adhesive on the stencil melted into the paint and caused one big smudge. Thankfully the weather stayed dry to enable us to quickly paint it green again. We will have to give that one more thought!
