Important for UK/European Readers
If you are in the UK or Europe, you will find the stitch names and terms in this video very confusing, and so I suggest that you do not try to learn with this video. If you do, the patterns you can buy in the UK and European shops will not fit with what you have learned, but you will be able to follow USA/Australian patterns.
As a beginner, it would be much better to learn the UK crochet terms first (if you live in the UK/Europe) and progress to learning to read US/Aus patterns once you have mastered the UK ones.
(I will post a video for UK crochet stitches (same stitches, different names) soon.)
