Quite a few years ago, I spun up a bunch of Ashland Bay multicolored merino sliver in Amethyst for my mom as a Christmas present. Some time later, she knitted it up into a comfy cozy cardigan for herself. She wore it a lot, but was telling me that she hadn't been wearing it lately because it had gotten so pilled.
So we decided to try out a trick I'd read online - shaving it with a razor! We figured it might make it better, and it probably wouldn't make it any worse, but just to be on the safe side, we started out under the arm where it wouldn't show.
I used a plain ladies' 3-blade disposable razor. I shaved the sweater with the fabric spread flat, using a downward motion. And it worked great!
Look at how much fuzz there is just from shaving a few inches:
You can also see that the section under that line of fuzz still has some pills.
And here's a handful, shaved off the back:
I've had various types of sweater shavers over the years, and I've got to tell you - this worked better than any of them! I wish I could remember where I learned it.
I've also read that you will need to shave a sweater twice - i.e. let it pill, then shave it; let it pill again and shave it again - but that after that all the fibers that are going to pill will have already done so and you won't need to do it again. Not sure whether that's true, but we were both really glad to have had such success with this trick!
Have any of you knitters ever tried this out?
Also, as an aside - I got an Instagram account quite a while ago, and am trying to train myself to take little daily photos. I put a link up there under my profile photo if you'd like to stop over there too :-)
