Materials Needed

To bring this celestial bloom to life, gather the following materials:

• Yarn: Worsted weight (#4) in 3 contrasting colors:
  • Color A: Deep indigo (approx. 100g)
  • Color B: Vibrant teal (approx. 100g)
  • Color C: Golden yellow (approx. 100g)
• Hook: 5.0 mm (H-8) crochet hook

• Other: Yarn needle for weaving ends, scissors, blocking mats and pins (optional but recommended for best results).

Step-by-Step Instructions

Important Notes: This pattern uses the mosaic crochet technique. You will work only in the back loop (BL) of the previous row. Carry the unused color loosely along the wrong side of your work. The square is worked flat in rows, then rotated to create the kaleidoscope effect. Read through all instructions before beginning.

Repeat for Pattern

Repeat Rows 3 through 12 until the square measures approximately 12 inches (30 cm) from the foundation chain. Be sure to end with a Row 12 repeat (a row of single crochet in back loops only). Fasten off all colors, leaving a 6-inch tail for weaving.

Finishing

Weave in all ends using a yarn needle, being careful to secure them on the wrong side of the work. Block the square to open up the mosaic pattern and ensure even edges. To block, pin the square to a blocking mat, spray with water (or steam lightly), and allow to dry completely. To create a larger kaleidoscope, make multiple squares and join them using a whip stitch or single crochet seam through the back loops only for a seamless look.

Your Celestial Bloom Mosaic Square is now complete. Enjoy the rich texture and luminous colors that make this piece a true modern heirloom.
