The method is older than it looks. String your beads onto the yarn before you cast on, warp your loom, or make your first chain. Then work as usual. The beads sit exactly where you placed them, held in place by the structure of the project itself. No sewing after. No guesswork.
It works across every discipline. A scatter of seed beads through a woven piece catches light between the threads. Glass beads along a crochet border read as jewelry. Pearl beads pulled into a shawl make the whole thing glow in a way that blocking alone never will.
