update since I posted this from Betsy via the comments below:
“Hi Everyone! Another box arrived today from a lovely group called “Yarns of Love” from the Maumee United Methodist Church. It had 50 hats and 7 scarves in it! It’s just like Christmas around here when the UPS man arrives these days. Thank you so much to all of you for helping make this effort such a success already. I can just picture the happy faces of the recipients. Blessings, Betsy”
If you need pattern ideas, there are lost of free hat patterns on Ravelry.
Kelly, from Creating a Family Home also designed a cute toddler ear flap hat for this project, so go check it out!
