Meet Josie Jakubovic.
Josie collected over 230 pairs for Knock Knock Give A Sock for her Bat Mitzvah at her school, Joseph Kushner Hebrew Academy.
Knock Knock Give A Sock is a college-started initiative dedicated to collecting socks for those in need, and getting communities to work together to help those who are experiencing homelessness.
