About This Infinity Cube Amigurumi Pattern
This pattern teaches you how to crochet an Infinity Cube fidget toy made from 48 small squares assembled into 8 soft cubes. It uses simple stitches like single crochet and half double crochet, with a special inc3 corner increase. Photos and assembly diagrams guide you through joining squares, stuffing, and connecting cubes to make a fully functional twistable toy.
The finished toy measures approximately 10 cm using the recommended materials and hook. Pattern is written in US crochet terms and includes a materials list, abbreviations, and step-by-step assembly notes.
Why You'll Love This Infinity Cube Amigurumi Pattern
I absolutely love this pattern because it turns simple squares into a surprising, interactive toy that both children and adults enjoy. I enjoy how the color layout creates a neat visual rhythm as you fold and twist the cube. The assembly stage is satisfying — stitching squares into cubes and watching the fidget mechanism come to life is always rewarding. It is also a perfect project for practicing consistent tension and neat finishing, which makes each cube look professional and tidy. Finally, I appreciate that this toy is practical and playful: it encourages fine motor skills and quiet focus.
Switch Things Up
I love how easy it is to customize the color palette for a different look; try pastel tones for a softer baby-friendly cube or bold contrasting colors for a high-impact fidget toy.
Want a mini keychain version? I often make smaller squares with thinner yarn and a 1.5mm hook to create tiny cubes suitable for bag charms.
If you'd like a chunkier cube, use a bulkier yarn and a larger hook; the cube becomes more tactile and squishy for sensory play.
I sometimes embroider numbers or shapes on the square faces before assembling to create an educational counting or matching toy for toddlers.
Try varying the border color on each square so seams form a subtle pattern when cubes are joined — this gives a mosaic effect when folded.
I like to add a loop of ribbon inside one seam as a pull tab for easier handling by small hands; sew it securely and hide the ends.
For a machine-washable version, use a washable cotton yarn and secure all seams with extra reinforcing stitches, and use polyester stuffing that is safe for laundering.
To make the cube quieter, add a small piece of fleece inside before stuffing to muffle crinkling and make the toy softer to squeeze.
If you prefer no-sew assembly, you can join squares with surface slip stitches and hide tails carefully, but I recommend sewing for maximum durability.
I often experiment with different corner increases — keeping inc3 but substituting a different middle stitch (e.g., DC) will change the face curvature and give a new look.
For a themed set, coordinate colors to match nursery decor or gift recipient preferences — alternating two colors across the 48 squares creates a striking striped effect.
Finally, I sometimes add tiny embroidered eyes on one face to turn a cube into a playful character while keeping the twisting function intact.
Common Mistakes & How to Fix Them
✗ Skipping the incremental stitch counts when making the square corners can distort the shape; always follow inc3 placement exactly and count stitches after each round to keep the square even.
✗ Stuffing the cubes too tightly will deform the cube faces and ruin the twisting action; stuff lightly with small amounts and adjust shape by hand as you go to maintain soft, even edges.
✗ Not hiding or securing ends before working the white border can leave visible tails; fasten off and weave ends into the wrong side or hide them when crocheting the edging row in white.
✗ Joining squares carelessly will leave weak seams and misaligned faces; sew with a stitch-to-stitch seam in the white sc row, pin or align pieces before stitching, and use small, even stitches for strength.
