I think Superwash Merino was invented for gift knitting.
But I really wish I had thought to make some kind of tag/speak to my boyfriend's mother about the alpaca scarf I knit him 2 Christmases ago. Since she's a knitter/crocheter, I thought she would know better than to put it in the washing machine, but...
He still wears the scarf. And it's still really soft. But the texture pattern I worked so hard on is unreadable now, and the colors muddied. So next time, I will make little tags with the care instructions like you guys said.
Nothing is worth doing that isn't worth doing badly.
