here's one being turned inside out... it makes a planter with a stand... they have cut one sidewall of the tire... they have cut a zig zag line aroung the side wall... must have used a 4 " grinder with an abrasive wheel on it... plunging the wheel into the sidewall would give you that short line then you could plunge for the next one... this gives the lovely scalloped edge to the pot... as well as having it on the edge of the stand... go get em...
