I loved these old socks. I wore them a couple of times (just enough sock to wear ruched above an ankle boot) before they went a bit stiff and felty in the wash. Then they were awkward to wear and a pain to put on. Now they need a new life, as I'm not willing to part with them yet.
To turn a pair of old socks into wristwarmers...
...you will need:
Scissors (not sure why I needed 2 pairs)
An embroidery needle (or any sharp needle that will take a fine/dk yarn)
A darning needle, for weaving in ends
Crochet hook (I used a 3.5mm for both yarns)
A small amount of yarn, in one or two (or more) colours.
Cut the feet off the socks.
Using the darning needle and some yarn (I used a dk weight cotton yarn). Blanket stitch around the cut edge of the sock.
When you reach your starting point, bring the needle and yarn under the first stitch you made to complete the round.
Remove the needle from the yarn, bring your crochet hook under the stitch you have just made, yarn over and bring through to make the first dc stitch.
Dc around. I made 2dc into each blanket stitch around. Fasten off the yarn when you have completed one round of dc.
Starting with a standing stitch, join your next yarn and continue in trebles around. As I chose an aran weight yarn for this round (I used a 3.5mm hook to keep the stitches tight), I crocheted 1tr in each of the first two dc, 2trtog over the next two dc and continued in this pattern around. Fasten off yarn.
For the final round, I rejoined the first yarn again using a standing stitch. I worked [dc in first two trebles, (dc, picot, dc) in next tr] around, fastening off yarn and weaving in ends.
I like the contrast of colour with the black and white sock. If you wanted a plainer finish, a simple row of dc would work just as well.
They are lovely and warm, and no longer neglected.
