The best choice is simply cut out the extra with a sharp sissors and glue it with neoprene cement. But using neoprene cement is now a lost art. We used to have to use neoprene cement to cement together our wetsuits before they had nylon or other backing, as they tore very easily. A seasoned diver would have repaired tears all over his wetsuit. So we learned how to do it:
1. Apply the neoprene cement to each side of the surfaces to be joined.
2. Let the glue dry completely apart from the other surface. This establishes a surface for the glue to bond to without the holes made by the closed cell neoprene. This takes at least an hour to dry, but some of us waited overnight.
3. Recoat the now dry surface with neoprene cement.
4. Let dry until "tacky," which means it will stick to your skin, but not come off on your finger. This takes about 10 minutes.
5. Join the surfaces together and press tightly. Start where the two surfaces are one, and work down to the open edges. Note that it is possible to stretch the neoprene so that the sides don't line up; prevent this by "tagging" the neoprene at certain areas while working to the edge to ensure that the edges line up.
6. Re-press the neoprene together to ensure that all surfaces are together. You can even roll the neoprene a bit to glue a greater amount into the seam.
Let the glued seam dry and cure overnight (if possible) before using. If it does pull apart, simply re-glue it once the suit is completely dry.
