I have the exact same question raised above - which no one has addressed yet (at least in this thread - maybe it is somewhere else on permies?)
I have a small area in a vegetable garden, that has 4 parallel raised beds (17' long), the last 2 not very clearly defined anymore, more like a pile of raised soil. I know the direction of the overall slope of the land and would like to create swales on contour, but I am stumped as to how to use the A level in this situation, with the piled up soil surface.
Should I pile up this raised soil to the side, trying to make the surface "flat" and then use the A frame?
