Many thanks to ravelling for submitting this to Ravelry for me.
Here’s her original notes: Although not technically a knit - this is an invaluable asset. The tutorial enables knitters to create cheap and personalised sock blockers to enhance their finished sock projects!

BTW, a few ravelers seem to have problem downloading the sock blocker template pdf from my blog, so I’m uploading it here for your convenience. But you’ll still have to go to my blog post for the tutorial.
