The five Platonic Solids in knit and crochet.
These are definitely not ‘solid’ in the usual sense of the word. They are soft and squashy like cushions but rather unconventional shapes for cushions. You might want to think of them as toys or novelty items for the home.
Any knitted or crocheted shape will be distorted when stuffed. All the shapes try to make themselves as round as possible, tending towards spheres. This is how the pattern acquired its name.
