In the depths of winter, our Canadian houses become very dry, the lower the outside temp, the drier. Today -14C.
One solution that I use, is to wash some wool sweaters and air dry them. I soak them in warm water with a bit of detergent meant for delicates in the washing machine. No agitation. Then, spin on the delicate setting, rinse and spin again.
Here is a photo of a draped sweater over a hassock. The mid afternoon afternoon sun is playing tricks with my light for taking a picture.
