I always start the whipstitching with a loop.
And then you just whipstitch through the front and back stitches. Adding beads every other stitch or every third stitch...or however you want the beaded edging to look. I use Piecemaker size 28 needles, the beads fit right over the eye. (The beads also fit over the John James size 28's too.)
Edgings like this are just without beads (whipstitched through the backstitching.)
When I get to the hanger, I put a small knot in my ribbon or cording, so that the end doesn't accidentally get pulled out.
My last stitch is always stitched through the beginning stitch. And then I thread the needle under the whipstitches and clip the end close.
