If you’re making a granny square blanket – or any project, really – choosing the right colours can be tricky. That’s why we’ve asked technical expert Becky Skuse to write this super-helpful guide to colour theory, or the art of putting colours together in the most pleasing way possible. Use the colour wheel that came with this issue of Simply Crochet to help you select the best yarns for your chosen project – just use the windows in the wheel to match your yarn shades to the correct colours, then follow the arrows to find out which shades are complementary, triadic, double complementary or create a tetradic square. Have fun!
