I learned a lesson, I washed a natural merino Irish sweater last year after having it drycleaned for a couple of years. I could not BELIEVE HOW DIRTY THE WATER WAS! After that I have washed every merino sweater I have bought. Cool water, handwash in the washer, tumble dry for about 5 min, lay flat to dry. Same for all the cashmere from QVC. I can't figure how someone managed to shrink one of these. Regular deterg and fabric softener. All come out perfect, I will never get something drycleaned that I can wash so easy.
