Fellow #facilitators, I need your advice: looking for a nice physical #thread/#ribbon/#cord that
- is available at arbitrary length, at least 3-4m (e.g., on a reel)
- stays flat on a table (doesn't warp or wobble upon every touch, moving or knocking over the objects it is meant to separate)
- is elastic (no permanent sharp bends remaining after usage)
- is reusable (isn't sticky, catching dust and lint; looks as new after cleaning with a wet cloth and a disinfectant)
Suggestions?
