Materials & Tools

Yarn: 100% cotton yarn in three distinct colors (DK or sport weight)

Soft Toy Stuffing: Synthetic or natural fiber
Blunt Yarn Needle: For assembly and weaving
Scissors
Stitch Markers (optional): To mark starting points during weaving

You'll only need basic supplies for this project, but select bold colors for highest impact!

Gauge

While gauge is not critical for this small functional piece, the straps should be firm and inelastic to keep the cube's structure. Test or adjust with the following suggestion:

Gauge Swatch: 40 sc × 4 rows
Produces a strap approx. 17-18 cm (7 in) long and 1.5-2 cm (0.6-0.8 in) wide with DK cotton and a 2 mm hook.

The straps shouldn't stretch much-if they seem floppy, use a smaller hook or firmer yarn.

Abbreviations List

ch - chain
sc - single crochet
sl st - slip stitch
st(s) - stitch(es)

Special Stitch Instructions

Single Crochet (sc):
Insert hook into stitch, yarn over, draw up a loop, yarn over, pull through both loops on hook.

Romanian Cord (optional):
Create a sturdy, textured cord for keychain loops. Alternative: simple chain and sl st for a basic loop.

If you aren't familiar with Romanian Cord, a regular crocheted chain will also work well.

Finished Size

Cube dimensions: Approx. 5 × 5 × 5 cm (2 × 2 × 2 in), depending on yarn/hook tension
Loop length: 10-13 cm (4-5 in), adaptable by chain count
Tassel: About 5-7 cm (2-2.75 in) long

The finished cube fits neatly in the palm and is sized for a bold keychain or bag charm.

The Pattern

1. Creating the Straps (Make 6 Total; 2 in Each Color)

Foundation:
- Make a slip knot, ch 41.
Row 1:
- Starting in the 2nd ch from hook, sc in each ch across (40 sc).
Row 2:
- Ch 1, turn. Work sc in each st (40 sc).
Row 3:
- Ch 1, turn. Sc in each st (40 sc).
Row 4:
- Ch 1, turn. Sc in each st (40 sc).
Finishing:
- Cut yarn, leaving a long tail for sewing. Pull through last loop to secure.
Repeat to make a total of 6 identical straps.

Each strap should be flat, dense, and about 18 × 2 cm (7 × 0.75 in). These form your weaving pieces for the cube.

*If you're not familiar with pattern language: Make 6 flat crochet strips by working 41 chains, then 40 single crochet stitches for 4 rows. Leave a long yarn tail to help you stitch the strip into a loop later.

2. Assembly of the Cube

Pairing:
- Fold each strap into a ring (bring foundation and final row together).
- Thread your yarn needle with the tail and seam ends together using whipstitch or mattress stitch for a neat closed loop.
Weaving Sequence:
- Step 1: Take two loops of the first color and interlock them so one sits through the other at right angles, forming the first linkage of the knot.
- Step 2: Take two loops of the second color and weave them perpendicularly through the first set, alternating over and under the original loops to maintain the cube's architecture.
- Step 3: Add two loops of the third color, carefully weaving them around the established cube structure. Alternate over and under as before, ensuring each color's loops are intertwined and untwisted for a symmetric pattern.
Stuffing:
- Before closing, gently insert stuffing through any remaining opening. The cube should be filled, but not tightly packed-a little bit of softness allows the knot to hold its geometric shape.
Final Securing:
- Sew or stitch closed any remaining gaps.
- Use the needle to secure all loose ends discreetly inside the cube.

Take your time with the weaving-the straps should create an intricate cube where each color is evenly distributed. It's important to follow the over/under sequence for a true Celtic Knot effect.

*If you're not sure about this section: Sew each strip into a band, then weave them together in alternating over/under patterns-just like making a lattice pie crust, but into a cube, not a flat sheet. Add stuffing before you finish closing up the last side!

3. Loop and Tassel

Loop:
- Decide which cube corner will be the top.
- With your chosen color, attach yarn and work either:
  - a Romanian Cord of 10-13 cm
  - or a simple chain of 70-80 ch.
- Secure by pulling end through last loop and weaving into the cube surface.
- Slip or tie your keyring into the cord.
Tassel:
- Gather all three yarn colors and wrap strands together evenly around three fingers or a card (about 20 wraps per color for a full tassel).
- Slide the bundle off and tie a knot at the top to secure.
- Attach the knotted end to a cube corner (ideally diagonally from the keychain loop) using your yarn needle and leftover yarn tails.
- Trim bottom of tassel evenly for a neat finish.
- Hide or secure any final tails inside the tassel or cube.

The loop makes this keychain functional, while the multicolored tassel gives character and swings freely from the cube for added flair.

*If you're new to patterns: Make a hanging loop of 70-80 chains, fasten to the cube, and add a bold tassel made from colorful yarn wrapped around your hand and tied to the opposite corner.

Assembly & Finishing

Tidy all visible corners by tucking or stitching stray yarn tails inside.
Roll the cube with your palms to even out the stuffing and shape the cube's lines.
Stretch and adjust each strap as needed so the pattern remains tight and doesn't unravel.
Examine the cube from all sides to make sure the weaving looks symmetrical; tweak if desired.

Take a moment to smooth out the cube-the best finish comes from careful adjustment at this stage.
