This is a GREAT activity to do with teenage girls! I used to unify my cabins of girls together as a camp counselor with this activity.
All you need is:
Colored letter-sized paper
Have girls chose whatever color paper they want. Have them write in the middle of their sheet (leaving room around the edges for cut-outs)
"I praise you because I am fearfully and wonderfully made. Your works are wonderful; I know that full well." - Psalm 139: 14 (NLT)
From there, give your girls time to look through and cut out things they like, or that help explain who they are. Have them glue their cut-outs around the verse they wrote on their sheets.
I had each girl hang up their collage by their bunks and told them it was a reminder that God created us all differently and beautifully. This is a great activity to remind us about acceptance of each others' differences.
