Do you have a serger or access to one? There is a foot that will apply string beads, pearls, ribbons lace to the edge of the tuille. I found that the serger was easier than that of a sewing machine as it finishes the edge of the tuille at the same time. But sewing machines can work. There are feet for the same available for them to. they come with adaptable shanks for the various types of mahcines.
I found that cutting accurately with scissors, not pinking shears, is the best with netting and tuille.
