Easy Knitting Project?

Start of my ‘Favourite Scarf Ever’

I wanted an easy project – something that was portable and that doesn’t require concentration. Favourite Scarf Ever from Lisa Bruce (sunshinewalks) seemed perfect.

Here’s the pattern page in ravelry

It uses one ball of (extremely beautiful) misti alpaca sock yarn – perfect (I have quite a few of those on my stash). This one is colourway 46.

What you see above is my third attempt (maybe fourth – I am losing track). It is an easy project, but I get to the end of a row and realise I haven’t done the double decrease properly and my attempts to undo one row always end in disaster. Or I forget to P2Tog at the end and get half-way through the next row before I realise everything is slightly out of alignment. I need to learn how to fix mistakes – is there any course on that?
