At least that's what I pd last time (might have been on sale)...then trace the size you want to save before cutting away.
This is what I do also, only I iron the interfacing to the back of the pattern so the the pattern is still clearly visible and then trace on a tissue or paper for the size of pattern I need at the time and fold everything all back up and keep it in a plastic bag.
