Making a concrete walk looks easy, but takes a lot of work to look good. You need to dig out the area, put in the forms, pour the concrete. Now you have to level it, wait for the right time and float it. Then use a broom to add the traction swirls.
If this is for the curb, then do it. If its for a path in your yard, consider alternatives such as the molds that look like stones or using real stones, or crushed rock, or other alternatives.
