I taught myself last night the single crochet (sc)
and on my first attempt I did find that I missed that last stitch on the row.
I used the basic crochet instructions on www.learntoknit.com
combined with some really good videos on www.youtube.com
(search for 'askauntesther'). I found the first video great but stopped the second video just before she turned to do the next stitch type, I might brave the third video when I've got a real grip of the first two!
I have so far managed to crochet about 8 rows without decreasing or getting in a muddle.
Just remember it is meant to be relaxing, and it wasn't easy learning to knit but we got there in the end.
