Does Merino Shrink Is There A Way To Shrink A Wool Sweater Without Felting It?

Is there a way to shrink a wool sweater without felting it? - does merino shrink

I just knit a sweater, and I tried (I'm 90% done with it) and seems a little too big (I think it can, because I lost 5-10 pounds between the start of the sweater. .. If he wanted one measuring spot ... and now).

I do not want to weave frog and again. I wish it would shrink, but I will not be felt, as I like the points of difference. Is there any way to the jersey without it turning into a large block of reducing odors? This is a point of Paton's classic merino wool. (100% wool)
