What makes Granny Square Designer special
Browse a curated library of granny square patterns – from timeless classics to playful florals. Most designs can be freely mixed and matched.
Pick how many rounds you want (usually 4–7) and assign colors to visualize your perfect combo instantly.
Choose your hook size and see how much yarn you’ll need – whether you use one color or several.
Note: Joining and border yarn are not included – so you can design them your own way.
Choose from 12 different bag designs and get a layout map with step-by-step assembly instructions. Most squares are compatible, so you can mix and match patterns and use your own color variations to create a truly unique bag.
Pick your blanket size from preset dimensions and let the app calculate how many squares you’ll need – based on your selected hook size. Choose which designs to include, fill your layout with any combination, and select a joining color to better visualize your plan.
Planning a sweater, pillow, or something entirely your own? Design your squares, see their size based on your hook, choose how many of each you’ll need, and get a full yarn estimate – even without a fixed layout.
Download a complete PDF guide with your square size, picture of your designed squares, crochet chart (diagram), written pattern, and total yarn needs – ready to print or take anywhere.
