All products from Frösö Handtryck have enclosed care instructions. For our cotton goods wash in 40 degree celcius with a gentle program. No spin or tumble dryer. For curtains we always suggest to first ventilate the curtains in fresh air or dry clean. Most of the linen and half linen demand dry clean. Check the care instruction for your specific product. Our christmas tree mats are made of jute. Jute can not be mashine washed. The print on jute is not heat fixated. You can fixate it by using a dry iron, no steam, on maximum heat for about five minutes. This will fixate the color but the mat can still not be machine washed.
