Remember that to tie a reef knot, it's 'left over right, right over
left' and for a granny knot, it's 'left over right, left over
It might help to make two granny knots and two reef knots. Then you

reef knot once you have turned it.
Alternatively, you could try sketching the knot after each
different turn and compare them that way.
