Over at the C & T blog occasionally different beading techniques from my book "All-In-One Beading Buddy are posted. This one just popped up. Though the book is now out of print, it is available as an ebook for $6.99.
Decorative bead strings secure braid or other objects to fabric.
1. Position braid, come up through fabric at A.
2. String sufficient number of beads to completely cover thread as it crosses over braid (either horizontally or diagonally), go down at B.
3. Come up at C, add beads, go down at D (same angle as A/B).
