Scarves For Nuno and Knitting

I bought some gorgeous scarves yesterday for nuno felting. The first two are different coloured versions of a blue peacock one I bought and sampled not so long ago:

The others are from a stall which sells 3 scarves for £5. It does make me feel a bit uneasy because it probably means they were made in some sweat shop in Bangladesh or China, but then a lot of the people who’ve turned their noses up at my extremely reasonable prices think I only deserve sweat shop wages anyway.

I recently finished knitting some pieces I want to make into arm warmers. They’re just rectangles made with pencil roving waste and very similar to a piece I made a while ago when I first tried the roving out:

The reason I haven’t joined the seams together yet is because I don’t know how to. I did ask on a group on Facebook, but I couldn’t really follow the suggestions. So, if you know of a tutorial or video which shows how to join knit stitch seams together so clearly that a cack handed 5 year old could follow it and do it neatly, I’d be really grateful! (no offence intended to left handers!) This is a ‘cuff’ I made by attempting to join seams together. I knitted 5 strands of plotulopi together to make a sample, then used the left over to join it up. This is the front:

And this is the dog’s dinner I made of joining it together:

Any help greatly appreciated!
