You need to lay out your beads and use a long thin needle. It's a pain in the rear. I did skating costumes. Never again.

If you have an embroidery machine, there are sashiko patterns which look very good. Babylock has a sashiko machine (expensive)

If you have digitizing software you can do your own sashiko patterns.

Keep your cat if you have one away from the beading. Goes for a toddler, too. My idiot cat tried to swallow the needle.
