As you visit the links for these seashell crafts, you'll see that the bloggers use a variety of different glues for their projects. Hot glue is popular with crafters because it sets and dries quickly, but it's not always the best choice when working with shells. The bond may loosen over time and the shells may pop off, especially if you're gluing shells to a surface like glass or porcelain. You'll have the best results and a permanent bond using E-6000, Gorilla Super Glue or Weldbond. You can also buy a specially formulated seashell glue that bonds to wood, metal, ceramics and other surfaces.
