How would you describe grabbing the hem of a skirt so you could carry something?

Solution 1:

I don't know if this is correct grammar (or even a word) but you could say something like. "The girl hammocked the apples in her skirt"

Solution 2:

It appears that we can use the word pouched in this sense.

Sally pouched apples in her skirt and headed home to make a pie.

Collins:

pouch verb
6. (transitive) to place in or as if in a pouch
