**I've had a few requests for the directions I wrote up to take to our YW activity . . . you can download it here.**
I found this idea while blog hopping . . . and used it to teach the Young Women (ages 12-18 from church) at our last activity. It took me several tries and over an hour to figure it out the first time. I ended up writing my own instructions for the activity that seemed easier to follow.
You only need 18 washers and 60" of ribbon. I think each necklace came out to around 2-3 dollars each. We used black satin ribbon, but I had also made one out of the pink grosgrain ribbon as well. The satin ribbon is easier to keep the weave tighter, but it gets twisted a lot and you need to straighten it out all the time. The grosgrain is harder to keep the weaving tight, but it's stiffer, so it's easier to work with when threading it through the washers.
