Here are some of the ways I display my beach treasures. Maybe they will inspire you to get yours out of the drawer and into the sunlight!
The bottles holding the sand are from IKEA and are $1 each. The tags are from Michaels and come in a package of 10 for about $4.
Both of these containers were purchased at Home Sense.
These containers were thrift store finds or, in the case of the small bottles on the left, held specialty cooking oil.
This is a tea light holder.
The holder on the left is from Home Sense, the bowl is a thrift store find, and the driftwood holder was a candle.
This is actually a drinking glass I found at Home Sense.
You just need to get a little creative and almost anything can be used to display your finds! Grouping the items together in groups of odd numbers works best visually.
