We all know how much linen creases - so much so I’ve avoided buying any for a while! Might reconsider though after reading this blog post from Sandra Betzina - sounds hopeful! Avoiding linen wrinkles
It does work well, along with the basic washing and drying 3 times, hot water and dryer before sewing. You want all the shrink out of the way at the beginning. You end up with the ever so slightly rumpled just back from safari look. I like it and not at all a street person.
Another secret is to ALWAYS use a press cloth with linen. Otherwise it takes a shine like nobody's business. Think of all those banquet tablecloths all starched and shiny. Not a good look for clothing.
My press cloth is silk organza and works well with linen.
I'm actually wearing real Irish linen pants I made and treated this way. Wash in warm, tumble dry warm until not quite dry then hand smooth quickly and I'm done. So comfy.
You might also like to try Brussels Washer linen, usually a 60% linen/ 40% rayon blend or the linen-cotton, bamboo or silk blends. I use the Brussels Washer a lot. It's a nice mid weight that's good for pants when it's warm or tops/shirts.
