I used some cut into short lengths to make a railing for a doll house, wood hand railing and bottom. Just a tiny spot with an ice pick or drill and they stay in place nicely. Also can make curved trellises for tiny roses and vines.
Doubled and bent, they make nice stiffeners for inside home made doll arms and legs. Victorian hats for dolls can use them in the brims.
Stiffen halos and wings for Christmas plays. Stiffens home made hat brims.
But the best are the crocheted ones, doubled and with tips upturned to capture and hold sleeveless garmets.
