I have made another one, same idea but a different design. This idea suddenly came into my head. Here are the materials I used. Twentysix small glass marbles, some brown knitting wool that looks like eyelashes, and some fabric cut from a dress I bought for 50p. If you want to have a go at making it this is how to do it. Make a long narrow sausage from the fabric, just wide enough to slide the marbles inside. Sew it together inside out then turn it the right way round. You need to make it as long as you want the necklace plus extra to tie it at the back.
Push the first marble inside to the centre, then take two pieces of wool about six inches long, you can use any wool, and wrap them round the fabric so you trap the marble. Tie it tight, then take a needle and thread the same colour as the wool, and put a few stitches through it so it doesn't come loose. Keep on adding the marbles, and seperate them with the wool, untill your necklace is long enough. I have 30 in the red one, and 26 in this one. If you don't have marbles you could use any small beads.
