I saw the idea for this a few months ago and I’ve been searching for the perfect shadowbox to do it in. Today I was in Hobby Lobby and they had them on sale and I found this one. (all this for less than $8!)
The picture is from our beach trip last year, the shells are collected from past years and I really love it!
You need a shadowbox, picture and various size shells.
I thought about gluing the shells in, but I liked how it turned out with them just hither and there.
