To get going you need to have a design.
Lately working with many clients; I like to start with drawings. Sometimes inspired by paintings. Sometimes by leaves. There are a gazillion starting places for designs.
Currently cement is my main materials....with various, lots of stuff, introduced..that is smushed into the wet concrete. Again only one approach.
I have on my agenda to makes some concrete stepping stones...good place to start..take pictures...but with my busy schedule..who knows when that will happen.
In the meantime, here is a drawing for a patio that I laid out in construction chalk today.
See ya soon...
