Crocodile Stitch
EW 2 rows
Triangle
1 scale : EW3 2rows (longer 4rows) EW2 1row, EW1 1row, EW2 1row, EW3 2rows(longer 4rows) Put the original loops back on the pegs.
To do another scale do the next 3 pegs the same way.
EW 3rows for short 5rows for longer
To stagger
EW1, EW3 2rows(longer 4rows), EW2 1row, EW1 1row, EW2 1 row, EW3 2rows(longer 4rows) Put the original loops back on the pegs.
 EW  3rows for short 5rows for long.
Repeat from beginning.

Round Edge
1 scale: EW4 2rows(longer 4rows), EW3 1row, EW2 1row, EW3 1row, EW4 2 rows(longer 4rows)put original loops back on pegs.
To do another scale do the next 4 pegs the same way.
EW 3rows short 5rows long
To stagger
EW2, EW4 2rows(longer 4rows), EW3 1row, EW2 1row, EW3 1row, EW4 2rows(longer 4rows)put original loops back on pegs.
EW 3rows short and 5rows long.
Repeat from beginning.

Rectangle Edge
1 scale: EW2 8rows (longer add 4 rows) Put original loops back on pegs.
Do the next scale the same way on the next 2 pegs and so on.
EW 4rows short, 6rows long
To stagger
EW1, EW2 8rows(longer add 4 rows) Put original loops back on pegs.
Then do the next 2 pegs the same way and so on. 
Repeat from beginning.

Please feel free to ask question about this technique, but the hard part is find your original loops to put back on the pegs. Trick go to the next peg that hasn't been touched and follow the line to the previous to find your loop. You can also too all the scales first and then put the loops on the pegs and it is easy that way. Trick is figuring what works best for getting those original loops back. This is an advanced technique and I would not suggest this for a beginner but a more experience loomer.

This is an example of a round edge.
