use your nails and fingers to keep design going the way
you need it to. BRUTE force is NOT bad. Don't be afraid
to do it, beads take ALOT to crack.
will have a couching thread that WILL NOT go down, sticks
out like a sore thumb, or crosses partially over a bead
due to a bead not being aligned with the others well,
just couch THAT thread down too.
Come up directly next to the thread,
and go down over it on the other side.
Tah dah! Hidden.
I usually will do this after I have everything else done
all at once.
