Easy, low-cost, no-mar way to attach edging
Rather than buy specialized edge clamps, make your own from common, inexpensive, and versatile spring clamps. Simply buy a length of tubular poly foam made for insulating 1⁄2
" copper pipe. Cut it into short lengths and use it in conjunction with any 2" or 21⁄2
" spring clamp.
