I have recently learned about an organization that provides slippers to women and children living in domestic violence shelters. It is The Pink Slipper Project. Slippers don’t have to be pink and they can be made using any pattern you feel comfortable using, for either women or children. The site also includes free downloadable patterns for knitting, crocheting or sewing slippers on the right hand sidebar. I can tell you from experience as a knitter and crocheter that those patterns are well written and easy to follow.
You will also find a list of sources for patterns here:
Please take a look at the site and consider sending a pair or two of slippers, or other items to this organization.
