Fair warning: this only applies to certain types of cheap particleboard pegboards, just as shown in my image. If yours is made of metal, plastic, or is only slightly different from what I bought at the hardware store, you might waste your consumables. The only way to make it more sturdy is to redesign it to use two rows of hooks, but I’m not interested in that since it works for my pegboard and maybe for yours as well—who knows—but you’ve been warned.
