Firstly the apologies .... I'm not that proficient with my videoing yet, so sorry for disappearing out of frame occasionally, hopefully that doesn't detract too much. Also, I'm still working up to narration - so I have subtitled :)
I use US terms for stitches, since I think they make more sense - even though I am from the UK!!
I start off with single crochet (known as double crochet in the UK), then half-double & double stitches. I also show front post and back post crochet stitches - in this video they are double stitches. Then to finish I have shown a popcorn stitch.
I hope this video is useful, feel free to comment on this video or request further stitch instruction.
