A granny square sweater is made by crocheting multiple small squares (granny squares) and sewing or joining them together to create a wearable garment. It’s a playful and modular design that allows for infinite color combos and layouts — from simple two-tone blocks to bright, multicolor explosions.
Depending on your style, it can be fitted, boxy, cropped, oversized, or even have a hoodie!
