Thanks voor the suggestions. I also discoverd dancing contained wool. I'm really allergic, even 5% is to much for me, so the yarn has to be totally free of wool.
I really liked the Fortissima Cotton Colori, hope I can find it
The suggested yarns don't sound familiar to me, I don't know if I can find them in the Netherlands. If I can't find them, can I also use yarn which is usually used for sweaters? 100% cotton for example, or a cotton blend?
