Office Decorating Project

We have a lot of large blank walls in the house, so we recently decided to add a little decoration to the office. We got the gorgeous pillows from Joom on Etsy and the picture frames from West Elm. Which leads me to ask, how much is too much? We thought 4 large frames would do the trick, but we find ourselves wanting to run out and get more. Will these pictures still be on the wall in 30 years? Like when I finally had to send my parents some new framed pictures because for the last 20 years, the only one they displayed of me was my senior high school portrait. gag. Better yet, will we replace these in later years with family portraits where we are all wearing snowflake sweaters, or khaki pants and white tshirts? You betcha!

This leads to the next conundrum. What happens when we have a second child? We won't have any wall space left.
