As the drape of a flexible cardigan is awfully tricky to
judge flat, use a friend or a dress form and drape your
cardigan and organza panel over it. This will take a bit
of adjusting and lots of pins! Even if you’re new at it
though, it just takes patience, and the willingness to
adjust here and there.
Remember, fold the raw edge under, and then use your pin
to keep that and the organza pinned in place. Your
organza should still be in one giant panel, so
adjustments should be pretty easy.
