I'm sure it's very minimal in terms of exposure, but I'd rather breath natural fiber carbon than: TEREPHTHALOYLCHLORIDE/P-PHENYLENEDIAMINE (PARA-ARAMID POLYMER) <img src="/images/graemlins/smile.gif" alt="" />

Good idea with the pipe cleaners. I've never dealved into wicks and natural cordage that might burn well.. this seems like a fun thing to try.
