Let's say you don't have a stick edger only a string trimmer. How do you put an edge on a side walk? Do you turn it sideways and make a smooth cut verticle? Do you lay it on it's side and cut the edge at a , say 90 d angle? Just wondering. I still use my Ryobi String with articulating boomer. I love it for this reason. Anybody have any pic's to post on this?
