I started putting down landscaping fabric in our back yard to help with weeding our garden and read the directions about needing landscaping hooks in order to secure it down. I didn't want to spend the money on something that will probably be flimsy plastic clips that will break or come up, so here's what we did at our house:
1. Grabbed 50 old metal hangers from a previous roommate (there's the free. Often you can find someone trying to get rid of them on freecycle as well).
2. Using a pair of wire-cutters, cut right below the twist on either side so you have the hook removed.
3. Cut in the middle of the bottom half.
Now you have 2 landscaping hooks! The best way to use them is to put the non-straight edge in first as far as you can, then put the other part in as far as you can. Depending on your soil, you may end up with a few inches of the metal showing, so make sure to space their entrance into the material far apart enough. This can be done while watching one of your favorite shows since it requires very little brainpower.
