Playing with marbles is really hot these days in The Netherlands. All the kids at school play with their marbles on the playground during their break. So.... a mom of two girls asked me whether I could make 31 marble bags for their oldest daughter to give away to her classmates for her birthday. Isn't that a great idea? I used pieces of almost all the fabrics which I have in stock here, so what a nice colourful sight must that be on her birthday!
