Over the course of the past couple weeks, I've picked up not one, but three nice vintage wool sweaters (none of which cost more than $3). This past weekend, I finally decided I should give them a good, cool sloshing about so I could actually add them to my wardrobe.
As I tossed them into the tub, I looked at their tags closer and was surprised to see how casually one sweater wanted me to treat, "the world's best virgin wool."
Granted, Puritan isn't known for being a top-of-the-line brand, but I've never given a 100% wool sweater a machine wash and dry and not had it turn out looking something like a miniaturized version of its former self.
In one case, an old sweater of mine that received such sad treatment ended up being tied into a small, knotted ball and became a favorite toy of one of our dogs (living it's life being occasionally shaken in a frenzy and lovingly referred to as, "the sweater ball").
Giving shrunken wool sweaters to a small dog as a plaything probably isn't setting a good precedence, but neither is machine-washing wool, I say.
And for the record, aforementioned dog has never destroyed another sweater (although loveseat cushions are another matter).
