You can probably see where this is going.
When I use self-striping yarn - which is a lot because I just LOVE me some stripey socks - I try to start at the same color so that the socks more or less match up.
After I caked up the yarn, I pulled out the centers until I got to a point in the yarn changes where I had the same shade of blue. Off I went on the sock #1 toe.
A few days later, I put sock #1 aside, out of sight in the main project bag, picked up cake #2 and started on the toe of sock #2.
Last night I decided to compare sock #1 and sock #2 to see how well I had matched up the stripes again, because I'm very good at starting up the socks at the same color and I was ready to admire my latest stripe success.
EPIC SOCK STRIPE FAIL.
A few minutes of tinking later and I'm back here tonight starting sock #2, this time at the correct shade of Caribbean blue.
I STILL do not have my second set of sock needles so I consider this a blessing in disguise. Now I have something to do on the train again.
Time to re-knit sock #2. This should last me for a few days while I wait impatiently for my new needles.
