We quite often get asked if Milburn DK is ok for garments - with being a lustrous and silky yarn I think people assume that it will be too heavy, or will drop, or not hold its shape. Or perhaps there's another reason that I've forgotten! Anyway, whatever the reason for the question, I can certainly answer it with a resounding yes. 😄
I've made a few, and I found that it didn't do anything unexpected. It didn't lose its shape or even particularly grow. I suppose if you blocked it hung up then yes the weight of the wool would pull it down, but you should be blocking garments flat really (unless you actually do want them to grow!). I tend to find that once you unpin things they always bounce back a bit, too.
Of course, rather than just say it, I can also demonstrate. Here's a load of garments made (very successfully, that is!) using Milburn DK - do take a look!
