You have to really turn the free leg in from the top of the leg & stretch it under/behind the skating leg. The free foot is flexed, sickled (cycled??) and pigeon-toed. Feels like you're trying to push your heel down to the ice. Turn the torso hard toward the skating side and let the free hip poke out.
. . . now rub your tummy & pat your head
Practice getting into the position at the boards. Remember the skating side has to push too, like it is trying to meet the free side - SQUEEZE
