## Questions & Answers

**Q: how do you care for this?  Is it washable and how do you do it?**
A: I wouldn't suggest washing it, but if stained, blot with hydrogen peroxide, it will clean anything. If you just want to clean it up, mix half vinegar and water, and spray it and let it dry, or if dirty, spray it, then cover with towel and twist the moisture out.

**Q: what sizes do you have**
A: from Medium to 4XL
