DIY grocery bag holder dispenser trash
1 - 1x6 @ 8 feet long
1 - 2x3 or 2x4 @ 12" long - cleat for hanging, can also use hanging brackets
1-1/4" brad nails
2 - knobs (nails or screw heads would work too)
5 - 1x12 @ 11-3/4" (I shortened these cuts so you can get all the cuts from the 1x6x8)
2 - 1x12 @ 18" - cut to fit
1 - 2x3 or 2x4 @ 11-3/4"
To hang, I cut a scrap 2x4 board 11-3/4" long and screwed it to the wall where i wanted the grocery bag dispenser hung. Then I just placed the grocery bag dispenser over the 2x board and screwed it down with a couple of 1-1/4" wood screws.
You could also hang with metal brackets or a picture hanging kit.
