Baby Smiles Easy Cotton is a soft all-season yarn made from a cotton-acrylic blend. The addition of acrylic makes the yarn extremely easy to care for (machine washable and ironable) and has a wonderfully soft feel. The yarn is certified according to Standard 100 by OEKO-TEX®, product class I, and is therefore perfect for sensitive baby skin. When working with this yarn, it is recommended to use needles with a size of 3-4 mm.
