Oooooh, I like this - it's fun.
I've been dipping in and out of Mason-Dixon Knitting, my favourite comfort-reading at the moment, and decided to have a go at log-cabin knitting. I like it a lot - it's simple and soothing but satisfyingly something-or-other (square probably). The yarn is some Sirdar Highlander Lopi, a long discontinued yarn I suspect. I've had it lying around for, um, years - I made some naalbinding socks using it (roughly copying the Coppergate sock) sometime last century in our more active re-enactment days.
Notice my mistake (the dotted line) on the first square - I couldn't remember the 'proper' way to pick up stitches so I did it my own way, resulting in it being back to front. Oh well :-).
