The need to knit socks..

..becomes more urgent than ever.
Today was the day for a thorough investigation of my knitted socks. I noticed that almost half of the pairs look like this:

How sad. And of course my favourite socks are most worn out. I tried to recover one pair some while ago. Frogging, "refreshing" the yarn and knitting a new sock upside down. I am not convinced.. It is so much work to unravel the slightly felted areas and the yarn just looks worn, even if I cut out the worst parts.
Too much work for a rather unsatisfying result.
Isn't that an excuse to knit more new socks? To buy more yarn? And first of all to find a method to - if not avoid - at least postpone the problem? I think the jawoll method with reinforcing yarn is not working for me.
I tried the slip stitch variation some while ago on the blue anklets and it seems to work fine.

Any other ideas?

In case you are bored or depressed with my sad pictures now, I encourage you to visit some other bloggers! There's this meme thing going on and I tagged some knitters that are well worth visiting because they have beautifully designed blogs with amazing projects and last but not least are enjoyable to read.
So, go and visit Amanda, an old hand in the knitblog universe, who will have to dive deep into her archives.
Over at Kira's place you'll find well travelled projects at the moment and examplary swatching.
Dorothee's blog impresses with contests (yippieh, I "won" a yarn swap) and brain-teasing pictures of mysterious holiday locations. Uh.. I like reading about other places..
Have fun!
