To cut an edge for a mulch ring?

What is your trick to cutting a fairly symmetrical circle around a tree? I've done a few and they don't always end up circular. Pretty close, but I feel like they could be better.
Simple way take a tape measure and from the widest part of tree trunk base/root flare measure out 2.5‘-3’ mark it with paint, then tie a sturdy string loop around tree, free enough that it will move around tree, paint a line around tree as you swing the line, starting and ending on your mark.
