What's included in this course?
Begin by getting to know Marianne. She shares her diverse creative journey, which started as a professional swimmer, to an international model, and now a crochet designer. Hear about the artists who have inspired her work.
Get an overview of the history of crochet: from its origins, the crochet boom in the 60s, to its rising popularity in the fashion industry, and its meditative benefits. Explore the materials needed for the course before delving into basic crochet techniques, from the slip knot, a variety of stitches, and using a magic ring. Then learn some more complex techniques like the double and treble crochet stitches.
Marianne then guides you through her creative process for finding inspiration. Discover how to find references in nature, and the artwork of other artists, as well as Pinterest boards. Sketch a rough draft of your design and create a crochet pattern. Next, choose a color palette based on the type of sea creatures you want to create.
The first piece Marianne creates is a crochet shell with the magic ring and crocheting in spiral. Then move on to the coral, which requires a similar technique but also the surface crochet method. Next, create your crochet fish before making two different kinds of crochet seaweed. Discover how to embellish and shape your pieces by learning decorative crochet techniques.
Transform your crochet pieces into a variety of accessories. Learn how to make a wearable brooch by adding a pin, discover how to create a decorative wall hanging by combining various pieces on an embroidery hoop, or see how to make a crochet aquarium arrangement in a glass globe.

Excelente curso
Muy bien explicado y muy buenos patrones!
It’s an interesting course—both enjoyable and a bit tedious at times. The instructor is very knowledgeable, and while the video angles aren’t always ideal, overall it’s a good and engaging course.
