A collection of eye-catching 3D effect crochet patterns for different sized blankets and throws, which all have an optical illusion effect. These cleverly designed geometric blankets look impressive but are actually simple to make because the designer only uses one technique, intarsia crochet, and simple stitches. There are 15 different designs in a variety of sizes from smaller throws through to large afghans. All of the crochet blanket patterns are written out in full and there are large charts for each of the designs for crocheters who prefer to follow charts. All of the blankets are made with Scheepjes Truly Scrumptious aran-weight yarn, which is made from recycled plastic bottles. This means that the blankets work up quickly and have a lovely drape as well as being visually striking. All of the patterns use the crochet intarsia technique and there instructions for how to prepare your yarn in separate balls before you get started so you don't end up in a tangle. There are also step-by-step instructions for how to do the crochet intarsia stitch including advice on changing colour. The patterns are written using US crochet terms, but there is a conversion table for UK terms, along with US/UK hook sizes, at the front of the book. The blanket projects include a variety of sizes, with the largest measuring 51 x 36 inches, but there are instructions for how to alter the size and drape of the blankets by changing hook size and adding borders. The 'Getting Started' section explains the concept behind the illusion blanket designs and the importance of colour, with advice on choosing alternative colours. This is illustrated with photos of swatches showing variations of the same design with alternative colour combinations. The front section will also includes information about yarns and hooks to use and other tools and materials featured. Some of the projects are finished with tassels and pompoms and there are instructions for how to make these and attach them to finish your blankets.
