I begin my bead sealing with the “ever-popular” Mod Podge. This also takes a while. Letting it dry in-between coats is essential. Keeping up with what you are gluing is a task. I’m sure there are some sophisticated ways, but not me. I use a styrofoam cone that I marked horizontally with masking tape. As I coat, I move the bead up the cone. I hope that little hint helps. If you use this method, you can start beads at different times, but still know where you are in the gluing process. Again, give it time. This can’t be rushed.
