Here's what we made yesterday morning. For Christmas I bought my niece this small bead and wire set from Joann's. And I bought her a boatload of safety pins and some elastic cording. I think the bead and wire set might have cost me 6 or 8 bucks, I can't remember. So it might have been a total of $12 at the most for the supplies, which is gonna go a long way toward some more crafts down the road.
I had seen a safety pin bracelet at Joann's and figured a 10-year-old could easily do that herself even if I had to help by tying off the ends of the elastic.
The first one she made was for herself. It's multi-colored and she wears it all the time. Yesterday, she said her best friend wanted one in green and clear beads. So that's what we did.
It's a simple thing but so perfect for girls this age. I counted the number of safety pins on the one at the store, which was 60, and used that number for my niece's bracelet. Her friend is smaller so we modified the number from 60 to 50.
