We live only a few hours from the beach so we go frequently and every time we go we come home with a load of new seashells. We have them in bowls, mason jars and on shelves through out the house. Last year we actually decided to celebrate Christmas at the beach and I instantly thought a beach/seashell tree would be fantastic. The kids and I sat down one day and painted them all with blue, blue glitter and white glitter. Then I cut all the jute for the loops and just hot glued them on the inside. The kids were able to hang them all their selves and even remembered picking some of them. I used a mini tree we already had with a fishing net as the tree skirt and just some blue mesh ribbon from the craft store for decoration. It was very easy, cheap and yet so meaningful.
