Or a great example of pooling... The upper parts of the socks were knitted on a 2.25 mm needle. It pooled badly, I considered to frog the whole thing and restart this pattern with another yarn or knit another sock pattern with this yarn. But the working needle cracked. Happened of course when I was in the train to Birmingham... any idea how frustrating it is to be in a train for over an hour, have to wait another hour at the railway station due of a cancelled train and sitting in the train back for one hour and a half WITHOUT any knitting to do?! Well, let's not ramble about these things in life (in future I'll always have a spare needle with me).
Anyhow, I don't have any other 2.25 mm needles, so I switched to a 2.5 mm. And the pools became stripes.
The Rollicks are fun and easy to knit. The yarn in use is Stroud Wool SuperSock yarn, colourway Pink and Rust.
