Whether you make changes seasonally; Or perhaps the changes come with a new favourite colour; I find myself moving items, or relocating them or removing them altogether - if only temporarily.
Here are some of my shelves as they look today:
I love white creamers. Big. Small. I love them all. I like to peruse the thrift stores and garage sales for beautiful ones. My collection has reached the point where I will only allow myself to buy a "new" one IF it is absolutely beautiful in my eyes. I must love-love-love it. No chips allowed. A little graze cracking is okay. Some discoloration is tolerable, but I must LOVE it. Even then, I sometimes force myself to donate an older one from my collection that is, well - a little less loved. :)
The cinnamon sticks are a leftover decoration from Christmas. I liked how they look year round, adding a bit of rustic charm. The patina on the silver pieces looks great against the white plates.
Even while I was taking these pictures, I relocated the three little creamers and the piece of coral to opposite sides - it's an never-ending hobby.
In my craft room, the shelves are decorated with both decorative and functional items. The jars of buttons are a favourite. Most of these buttons are vintage. I remember many from when I was a young girl. My mom could not - or would not - throw out a button. She'd say "you never know when you might need it!" So now my mom's hoarding habits are a beloved feature on my shelf.
Although not a shelf, I like the black iron decorative wall hangings. It adds a nice touch to the empty wall. I placed some pretty card stock paper and a flower.
