The cross is above the skirt with a pointer aimed at the piece it is for
Put your pin at your measurement for your hip on the tape,
now put that in the cross above the skirt and
make the numbers touching the hem.
Next do the numbers just dangling
below the first set of numbers.
If when marking these numbers the tape goes into your waist or above
take the pin out and move it to your waist measurement
on the tape and continue.
