When weaving in thread tails in right angle weave, you want to make sure that your thread does not cross between beads where it will show. While you sometimes will see thread between beads in right angle weave, you do not want thread to show between units. The thread should always be going in a circle that connects the beads.
Knotting your thread is important when using right angle weave because this stitch is more fabric-like than other stitches. It is also important to pay close attention to your tension, as right angle weave it more likely to pucker than other beading stitches.
If you are weaving in your thread tails in a piece of netting, follow the same directions as you would for right angle weave. Make sure that you tie several half-hitch knots in between beads, and be careful not to pull too tightly on your thread as you weave.
It can be helpful to use a small drop of glue or fresh, clear nailpolish to secure any half-hitch knots that you tie when weaving in your thread tails in either of these stitches.
