Follow these steps to remove crayon stains from felt:
- Very carefully scrape the residue off, taking care not to pull out the fibers.
- If any residue remains, try brushing (the method of using a stiff-bristled brush to gently remove dried stains and spots).
- In extreme cases, use a razor blade to gently scrape the excess.
- Use this as a last resort as it will remove some of the fibers.
