Come up anywhere near an end of your section, at a crack
between two beads.
Here is a show showing the thread
and the rows involved.
Pull thread from underneath till
thread POPS past the beads and onto the threads through
And pass over the second row and
the third row.
Repeat as far as you need, this goes
much faster than it sounds.
Once on the inside of your shapes, if the cracks are
aligned for it, you can pass over three beads.
You might need to tuck the thread down if it doesn't
hide enough, see that on the next page.
