How to speed up hand beading sewing?

Make your own small tooling. A small board with a nail nailed to one side, a thread tied to the nail, and a needle stuck to the other end. After the needle penetrates the bead, the bead slides to the bottom through the plate without winding the thread, which improves the threading speed. Needle and thread beading is a craft, which requires the accumulation of time and the precipitation of experience, and the mastery of skills also requires constant practice.
