Upcycle old flip flops at Old Navy

Spring is here and summer is right around the corner. It's time to 
 break out the season's favorite fashion combo, shorts and flip flops. 
 That grimy pair from last year won't cut it. Before you upgrade, drop 
 your old pair (or three) in a designated bin outside your nearest Old 
 Navy and put them to good use. The deadline is May 21st.
