To hold a lot of pliers, it's easiest to just hook them onto the edge of a piece of wood. A lot of pliers go in a small amount of space that way. The piece of wood in this holder is tapered towards the top edge, so that it doesn't force the handles too far apart. It's really only about half full with pliers so far.
Just in case you didn't know this exists at Walmart for less than $4 per roll. I'm about to glitter everything! Votives, notebooks. No more Mod Podge and glitter nightmares!
