Best feathers I ever used were from Michael's craft store. They had short quilly feathers that you could lay all over your lee for more stimulation when they squirm around and they tickle themselves from moving too much. Soft frilly feathers for using over the belly, thighs, and arms. My favorite was this 3 or 4 foot long peacock like feather that you could twist around the lees body just about anywhere and it left the most satisfying tickle trail, and made them hot, giggly, and not sure whether to beg for it to stop, or if you hit other places; they might just beg for more.😉
Hope you find the right ones, and have a blast.🤘
