|This is not a sewing class, but many people who sew also like to do other hand crafts. And you can link crochet and sewing (there are even a few examples in the class). So it seems like there will be enough interest to warrant reviewing this class here.
If you do not know how to crochet but would like to learn, I highly recommend this course.
The class covers the basic stitches: how to start, chaining, single crochet, double crochet, and half double crochet. Also covered are how to read a pattern, how to read a chart, tools required, how to do a gauge, blocking, and a few simple projects.
The instructor, Vicky Howell, has a friendly casual manner. She is very encouraging. One of the best things about her teaching is her telling us new crocheters that no, our work won't come out perfectly and that's okay. Each technique is not just shown, but taught. I understand the stitch, I understand how they compare to each other. Not everyone who knows how to do something can teach it; Vicky can.
The video and sound were very good. Since this is a video, not live, class I was able to replay sections that I needed to see more closely. My only complaint on the format is not the class itself, but the Craftsy site - sometimes the servers must get overloaded so you can't access the video for a while. That is very inconvenient. There are other aspects of the site that are nice. You can make 'video notes' at points in each lesson. I marked some spots where she taught key techniques that I might not remember.
There are 'course materials' that accompany the class, which are PDF files. These are helpful, and include both the projects done in the class and some additional ones. I initially was slightly disappointed with one aspect of the material: In the explanation of the stitches, she does not mention how to start new rows. But I figured out that this is because the steps are actually included in patterns, so putting it in the stitch explanation might cause people to do some steps twice (and mess up their crochet project because of it).
While there are a certainly many techniques not covered, this class gives a very strong foundation to work from. It meets it's intended goal of teaching the basics of crochet. I intend to crochet myself a felted dressy clutch purse, and an afghan. These are now both within my abilities as a crocheter.
Update: i just found a great reference for learning how to crochet (or knit) on the Lion Brand website.
So if you want to try that first it might be enough for you. If not then you can try this class.
