I collected toilet paper rolls for quite a while to organize my computer cables (another suggestion I saw on Pinterest).
Because I had so many leftover after I finished organizing my cables, I decided to search Pinterest for another project. That's when I saw the faux iron artwork project.
I cut all my toilet paper rolls into 10 slices or rings each By flattening the roll and then cutting it (no need to measure, just estimate the width as you cut...it doesn't need to be perfect).
I then just started gluing them together with a hot glue gun.
As you can see I started with six in the center, and then just added a new piece in every space, symmetrically.
