This is why I don't do knitted socks for myself.
Remember these slipper socks? I just had finished them in January and now I've worn a hole in the sole. Could be because they were not knit at a tighter gauge, could be the yarn type, could be I wore them too much. And yes I do drag my feet, one foot in particular because I have a slight scoliosis back problem - so I cannot fix that, but I really like warm slippers.
The crocheted ones seem to be holding up better but I prefer knitted ones.
So I fiddled around with a generic garter stitch type slipper and left the sole part until last.
I picked up 12 sts at the black stripe and knitted back towards the heel, picking up and knitting together the ends of the cuff stitches.
The plan is that when I wear a hole in the sole, I can unravel it and re-do it. We'll see....
At least they are bright and cheery!
