For the ornament: I took a clear glass ornament, pulled out the hanger and used a funnel to fill it up about halfway with sifted sand. Then I put a few tiny shells and beach goodies that i got out when I sifted the sand from the beach on top. Once I had everything in there I put some hot glue around the hanger and reassembled the ornament. Let it dry, then hang on your tree! I forgot to take a picture, but it really did come out nice.
For the Beach Jar: I had a hurricane glass vase laying around. It was actually from the centerpieces at my sisters beach wedding! Then I took the rest of my sand and poured it straight in. My boyfriend works near a beach that is not accessible to the public so it has an amazing shell collection. He picked me up some nearly perfect conch shells. I put three in my vase. Then I topped it of with a picture of my two pups walking down the beach, it is actually the same beach that I got the sand from! I love the way it turned out. At the moment it is displayed next to my fish tank, I thought it might give them a little hope, haha!
