A collection of eye-catching 3D effect crochet patterns for different sized blankets and throws, that 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 work crochet intarsia including advice on changing colour. Please note that 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. There are instructions for how to increase the size of the blankets by adding a border as well as decorative details including tassels and pom poms. There are also instructions for how to alter the drape of the blankets by changing the hook size you use.

This is illustrated with photos of swatches showing variations of the same design with alternative colour combinations.
