The granny square may be one of the most familiar motifs in twentieth-century crochet, but its history reaches much farther back than the 1970s. For collectors and designers, the best examples reward close study of motif structure, joining, palette, fiber, border and workmanship.
A Motif With a Long History
The Craft Yarn Council traces published directions for the familiar square motif to an 1890 Weldon & Company publication, where it offered a practical use for remnants of yarn. That economy is fundamental to the form: small amounts of many colors can become a coherent textile through repetition.
What Is a Granny Square?
A traditional granny square is generally worked outward from a center in rounds. Clusters of tall stitches are separated by chain spaces, with increases at the corners allowing the motif to remain square. Variations are enormous: solid squares, floral centers, concentric color rings, dimensional flowers, geometric motifs and elongated or rectangular adaptations all belong to the broader visual family.
Not Every Crocheted Square Is a Granny Square
Collectors should resist using “granny square” for every modular crochet blanket. Some squares use entirely different stitch structures or imitate quilt blocks, flowers, stars and medallions. Identifying the actual motif can lead to a named pattern, designer or dated publication.
Why Modular Construction Matters
Squares made portable handwork possible: a maker could complete small units individually, use remnants, and decide the final scale later. That construction also allows close examination of workmanship. Compare motif size, tension, corner formation, color sequence and the way ends were secured.
Joining Methods
The joins can dramatically change the design. Dark joining yarn can create a stained-glass or grid effect; matching yarn can make motifs flow together. Whip-stitched seams, slip-stitch joins and crocheted joins produce different ridges and flexibility. A later repair often announces itself through different tension or yarn.
The 1970s Revival—and the Dating Trap
Granny squares became extraordinarily visible in later twentieth-century fashion and interiors, which is why saturated brown, orange, gold, green and multicolor blankets are frequently assigned to the 1970s. Some certainly belong there. But the motif is much older, and it never disappeared. A “1970s look” is not proof of a 1970s date.
A Documented Mid-Century Example
The Smithsonian's Anacostia Community Museum holds a mid-twentieth-century synthetic-fiber granny-square blanket composed of colorful floral squares joined with brown yarn. Such documented objects help anchor the technique in material history without implying that every visually similar blanket shares the same date.
What Collectors Notice
Especially compelling examples may combine consistent handwork with sophisticated color planning, unusual motifs, a strong border, substantial size and good structural condition. Provenance can add another layer: knowing who made a blanket, for whom, and in what household context transforms an anonymous decorative textile into a documented object.
What Designers Notice
Granny squares carry both pattern and texture, so they can act almost like a movable piece of folk art. In a restrained room, a multicolor afghan can provide the dominant pattern. Cream or two-color examples can add handwork without overwhelming a traditional interior. Earthy palettes can bridge cottage, Arts-and-Crafts-inspired, bohemian and collected spaces.
Condition and Conservation
Joins and outer corners are common stress points. Look for broken yarn, separated motifs, stretched corners, stains, fading and repairs. Avoid hanging a heavy blanket for long periods from a few loops or corners. Fold with broad support and rotate folds during storage.
How to Date One Responsibly
Use provenance and exact pattern matches first, then fiber, joining method, motif construction, border, dimensions, wear and palette. If the evidence only supports “mid- to late twentieth century,” that is more useful than an unjustified exact decade.

Design Value Beyond Market Value
Textiles carry design through scale, drape, texture, pattern rhythm and evidence of handwork. Those qualities can make a modestly priced object central to an interior even when its maker is unknown.
Evaluate the textile from across the room as well as up close. Ask whether its palette connects other materials, whether its texture softens hard surfaces, and whether its proportions give the composition authority. Decorative usefulness is a real form of value, but it is not a universal dollar premium.
