The basic and open sprang techniques can be combined to make lacy patterns.
Diagonal patterns are best, since the rows of holes are staggered.
These directions are for a diamond figure of open holes on a tight background. I think of my sprang as growing from the top down, so this explanation reflects that. Holes can be thought of as in columns which skip every other row. Add a new hole to the right, temporarily close the previous holes, add a new hole to the left. Close the right and left columns of holes, keeping the middle one.
