If you love pebble mosaics as I do you definitely would enjoy pathways made of them. You would also enjoy an amazing pebble carpet in your patio if you could make one. The examples that you see on photos are made by Jeffrey Bale from Portland, Oregon. To make something similar you definitely need to gather a lot of different pebbles but the result worth it.
You can gather differently colored pebbles but you can also buy them. They are inexpensive but in any case it takes a lot of time to sort them. Large plastic nursery pots work well for the sorting and wetting. Check out full instructions of the process that Jeffrey uses for its pebble mosaics.
