In the 2 years I've been making Wrapstar Baby Carriers, I have never had an  issue with materials or workmanship. Recently, there have been 2 carriers that  have had internal canvas shrink in the washing cycle. Both were from the same  order of canvas.  Because of this, I am cautioning owners  to spotclean their Wrapstar instead of washing in a washing machine.  This is  a cosmetic issue only, and does not affect thesafety of the carrier. In an  effort to always improve quality, this situation is being  looked into. So until further notice, the recommended cleaning method will be to  spot clean as needed.
