After my first few attempts at draping the lace I decided to try a different method.
I wanted to see how the swoops of lace would lay differently if there was a slit in the lace verses simply having the fabric gathered.
As you can see, a slit in the lace can create a longer and slimmer drop in the fabric.
However, you do lose a bit of the fullness that was present from just gathering.
I think I will go with a small slit, to add a bit of length, but hopefully keep much of the soft fullness of the gathered drapes.
