I’m making some toys for use on a hardwood floor and want them to not slide too easily when bumped, so I figure I need something grippy to put on the bottom. My best idea so far is to seek some of the same material folks are using to engrave/cut rubber stamps (this link from other posts here seems promising). Anything actually adhesive is out — that’ll just become ineffective after picking up dust from the floor. Maybe also engraving/scoring some pattern to make it more grippy?
But before I go shopping… has anyone else faced similar issues? What kind of materials do you use?
