“Do I need to block socks?”
Blocking your knitting makes it relax after all that tense knitting. The fibres behave naturally once they’ve had a soak and the true size and shape of your garment is revealed. I’ve just finished knitting a pair of socks for my husband. This very delayed birthday present (they weren’t finished in time for August…) will now be a Christmas present and so I wanted to treat them with the proper respect.
Blocking is particularly important for socks because, being a tube, they can really shrink in on themselves very easily. If you’ve chosen a pattern with any kind of design (mine had an 8-stitch cable on either side of the leg) then this can be hidden until the socks are blocked. These details are the parts that you’ve worked hardest on, and they really sell handknit socks, so we want to show them off as much as possible.

Step 1
Soak your knitting
The first stage to blocking is soaking your knitting in some kind of hand-wash detergent. I used a sachet of Soak and left the socks in their bath for around 15 minutes.

Step 2
Slide your knitting onto a sock blocker
After waiting patiently, it’s simply a case of gently ringing out any excess water and sliding the socks onto some blockers.
Step 3
Leave your socks to dry
They have to dry naturally, and I left mine in a sunny window for a couple of days (although, I’m not sure how many more sunny windows there will be between now and Christmas).

Latest deals from trusted retailers
Since blocking, my socks have almost doubled in size and the cable detail has bloomed so that it can be fully appreciated. Now, when he unwraps them on 25 December, my mister will be presented with beautifully finished socks.
Happy knitting!
