Step-by-Step Pattern Instructions
- Round 1 (The Sun Center): Using your yellow or gold yarn, ch 4 and join with a sl st to form a ring. Alternatively, make a magic ring. Ch 3 (counts as first dc here and throughout), work 11 dc into the ring. Join with a sl st to the top of the starting ch-3. Fasten off yellow. (12 dc)
- Round 2 (Radiant Rays): Join your orange or secondary warm color in any st. Ch 2, work a cluster st in the same st. *Ch 2, work a cluster st in the next st.* Repeat from * to * around. Join with a sl st to the top of the first cluster. Fasten off warm color. (12 clusters, 12 ch-2 spaces)
- Round 3 (Transitioning to a Square): Join your main outer color (neutral or contrast) in any ch-2 space. Ch 3 (counts as dc), (2 dc, ch 2, 3 dc) in the same ch-2 space to form the first corner. *Skip next cluster, work 3 dc in the next ch-2 space. Skip next cluster, work a corner (3 dc, ch 2, 3 dc) in the next ch-2 space.* Repeat from * to * around, ending with 3 dc in the final space. Join with a sl st to the top of the starting ch-3. (4 corners established)
- Round 4 (Expanding the Square): Sl st across to the first ch-2 corner space. Ch 3, work (2 dc, ch 2, 3 dc) in the same corner space. *Work 3 dc in each space between 3-dc groups across to the next corner, then work (3 dc, ch 2, 3 dc) in the corner ch-2 space.* Repeat from * to * around. Join with a sl st to top of starting ch-3.
- Round 5 and Beyond: Repeat Round 4 until your square reaches your desired size. Fasten off and weave in all ends securely.
Finishing & Helpful Tips
- Block Your Squares: Take the time to block your finished solar squares. Pin them to exact measurements and lightly steam or spray them with water to ensure crisp corners and neat edges.
- Weave as You Go: Because this pattern involves changing colors between rounds, weave in your yarn ends as you finish each round to save time during assembly.
- Consistent Tension: Keep your tension even—especially when transitioning from the circular center to the square rounds—to prevent the motifs from warping or curling.
- Joining Methods: Once you have a collection of squares, join them using your preferred method (such as the mattress stitch, whip stitch, or a continuous crochet join) to create blankets, pillows, or tote bags.
