I’ve never outgrown my love of bulletin boards. I had one in my room when I was growing up and I continue to hang them in my home to collect the things that come my way and catch my eye as I move through my life.
Refrigerators count too. What ends up on them is a bit more transient, as they tend to collect things that I need to be reminded of in the near future so notes, etc. tend to go up and come down as events pass by.
The refrigerator in our new home has a wood front and isn’t magnetic. As a result, I hung a magnetic board in my back hallway so I could continue to enjoy the magnets I’ve collected over the years.
