quirky frame gallery wall

so heres my latest project I'm rearranging my living room and I asked my dad to make me some of these frames I've been seeing all over etsy lately... I knew he had a jigsaw and router...and I pleaded with him and my mom to make me my christmas present early so they made me a 4 foot letter J and these stinkin cute frames.. He also came up and hung my thrift store chandelier..that I painted from mustard to cream..and hung above my dining table. So I'm in the process of redoing those little side tables in creams.. and am debating leaving the frames open or filling them with our new family pictures and some quirky prints....what would you do with them....also my parents are thinking about making these bad boys and selling them in their etsy shop... would you buy them? I just love mine! It makes my living room feel like a retro ice cream shop.. I just love them!
