I love the beach. The first beach item I made was on a pocket. I embroidered a beach scene on the back pocket of jeans. It took me a very long time because I covered the entire pocket but it was worth it. I chose bright colors so it would really stand out. Those pants have since been worn out but I took the pocket off so I could sew it onto another pair of pants.
When you are sewing jeans, learn how to hem jeans with the original hem.
