Microsoft Majorana Crochet Cube Set Decoration Pattern

What Makes This Pattern Special

Meet the Microsoft Majorana cube, a soft little tribute to one of quantum computing's most fascinating concepts, reimagined in yarn. This beginner-friendly pattern walks you through stitching six identical squares, each one worked flat in single crochet, then joined together to form a tidy 4-inch block that sits nicely on a desk or shelf. With worsted weight yarn and a 4 mm hook, the stitches stay plush and defined, giving the finished cube a satisfying, squishy texture you will want to keep turning over in your hands.

You will practice the most basic crochet stitches, simple chain spaces, and straightforward whip stitching to seam the panels. The rhythm is steady and meditative, with each square built row by row until you have six matching faces ready to assemble. Once stitched up and lightly stuffed, the cube holds its shape beautifully, measuring approximately 4 inches tall and 4 inches wide. It is a charming way to bring a touch of physics-inspired decor into your home, and a wonderful first project for anyone curious about amigurumi-style construction.

Bring It All Together

1. Stuff hat body firmly with polyfill for stability. Shape as you go, pressing and molding to match the reference photo. Add extra stuffing to the base for a sturdy foundation.

2. Check all seams are secure. Gently tug each attached piece to test. Trim any loose yarn ends with sharp scissors. Weave in all remaining tails with a needle, passing through at least 3 stitches in each direction to prevent unraveling. Give the finished piece a gentle squeeze to distribute stuffing evenly and shape the final form.

Helpful Tips and Cleaning Advice

These tips will help you crochet each cube evenly and finish the set nicely with your 4 mm hook.

• Place a stitch marker in the first stitch of every round so you can find your starting point easily and keep your seam straight.
• Check your gauge by crocheting a small swatch before starting; matching tension helps all six cubes come out the same size.
• When decreasing, work both stitches together slowly so the fabric stays flat and does not pucker at the corners.
• Stuff the cubes firmly but evenly, adding small amounts of fiberfill at a time so there are no soft spots or lumps.
• Leave a long tail when fastening off so you can stitch the final side closed securely and weave the end in well.
• Count your stitches at the end of each round to make sure you have not added or dropped any, keeping the shape neat.

Follow these care instructions to keep your finished cubes looking their best over time.

• Hand wash gently in cool water with a mild detergent, then squeeze out extra water without wringing.
• Air dry flat on a clean towel away from direct sunlight to prevent color fading.
• Spot clean small marks with a damp cloth and a little soap rather than washing the whole cube.
• Store the set in a dry place to protect the fiberfill and keep the shape well.
