Crossweave is very similar to right angle weave, but instead of one needle, your using two needles. Here is a quick how to of how I did this...
Using two needles, add three beads onto your beading thread to start and then add 4th bead and go through w both needles through the 4th bead. Then add a bead to both needles, then add another bead and go through that bead with both needles. Repeat....add a bead to both needles, then add another bead and go through that bead with both needles. Keep repeating until desired length.
Crossweave Necklace. I change uses for this necklace, I sometimes add a pendent, or my name badge or if in my craft room I use them to hold my glasses. :)
