As I am pursuing my technical writing degree online, I am accustomed to online classes. They require about 4 hours of work a week per credit, have special chat rooms and video tutorials. To my surprise, so do the classes at Crochet Insider. The discussion boards allow you to read the material, comment on it, and respond to the comments of your classmates. There are links to helpful websites and video tutorials not available to the general public.
It's nice that there are no hidden fees or additional books to purchase. The prices are reasonable. Pay for the class with Paypal and you're done!
The classes open your eyes to more details of the topic than you ever realized existed. As details are an important part of crochet work, awareness of the how and why make your work that much better. As an additional plus, you will make friends and connections with your classmates. It can be very interesting to see how different people interpret the same thing in such diverse ways!
I highly recommend to anyone considering taking a class at Crochet Insider to do so. Do not hesitate to email Dora if you have any questions - she's terrific at getting back to you! These classes are reasonably priced, and the investment in yourself and your craft is worth every penny.
