Thanks to Karen for her encouragement and thanks to Youtube for its great videos (videos from CyberSeams are the best!), I've completed my first knitting project - a simple scarf of Garter stitch. Videos made learning so much easier, I admire people who learned from books with just 2D images.
Garter stitch - every row, front and back have the same pattern.
The scarf looks OK on the whole, but I know a few flaws. I can't hide the frayed knots of the yarns, I can only 'adjust' them so they are only visible on 1 side of the scarf, that becomes the back of the scarf. And binding-off was the most tricky part, everything was good until the 2nd last stitch :( I didn't know how to save it. However, I learn from my mistakes, hopefully next one will be better :)
I used 3 balls of yarn for that, it's kind of short, so I've prepared 5 balls for my next project. Knit stitch on every row bores me, I'm going to try the Stockinette Stitch this time.
