Easy & Free Crochet Tri-Square Purse Pattern for Everyone

A seamless blend of double crochets, half-double crochets, and single crochets brings each square to life, lending the purse an elegant yet robust texture. What truly sets this purse apart is the sequence of precise joins and creative color variations that allow room for personal expression. Whether used for daily errands, outings, or adding a touch of handmade artistry to your wardrobe, this bag is both aesthetic and functional.
Practical and stylish, the tri-square purse is ideal for those seeking a compact, handmade solution for carrying small essentials. With straightforward stitches and repeatable techniques, this project offers both beginners and experienced crocheters an opportunity to master tension, experiment with color, and produce a chic accessory with a personal touch.

The pattern begins with the classic magic ring, from which chains and double crochet stitches radiate to create the body of the squares. Corners are formed using chain spaces, which give the bag its symmetrical triangular shape when assembled.

A subtle detail worth noting is the use of half-double crochets to transition smoothly between rounds, ensuring that stitch placement is perfectly aligned.

Midway through, alternating rows of double crochets and chain-one skips introduce textural interest, while the skillful placement of two double crochets in corner spaces forms the foundation for strong and structured shapes.

They finish off the final rows of each square with single crochets, which not only add durability but also create a neatly defined edge.

The designers use a clean and innovative slip stitch technique during assembly, where they join the back loops of adjoining stitches row by row for a flat and polished seam. Moreover, they seam the open ends of the assembled triangles with a methodical approach to create the main body of the purse.

A chain-based strap, adjustable in length, adds to its functionality while blending harmoniously with the design. Additionally, the option to switch yarn colors at strategic points gives every purse a unique aesthetic.
