This is a nice rayon (58 %) and cotton (42 %) summer yarn (50 g/110 m). Of course this kind of yarn splits somewhat easily, still the fabric is lovely and the shine is delicate. The yarn is produced by Schachenmayr Nomotta. For some reason, the database here shows some discontinued yarn by the same manufacturer and under the same name but with different weight and containing acryl.
