  Approx. 1800 yds total (adjust based on your blanket size).

Step-by-Step Instructions

This pattern creates a beautiful 4x4 grid of 16 squares, each worked in the round. Don't be intimidated – the repetitive nature of the rounds makes it a relaxing, meditative project once you get the hang of it. Let's dive in!

Square Motif (Make 16)

Each square is a burst of color, built from the center outwards. Follow these rounds carefully, and you'll have a perfect 6-inch square every time.

Round 1: The Sunburst Center

With color A (Saffron Yellow), make a magic ring. This technique creates a tight, seamless center.

1. Ch 3 (this counts as your first double crochet).
2. Work 11 double crochet (dc) into the ring. You should now have 12 dc total (including the initial ch-3).
3. Slip stitch (sl st) to the top of the ch-3 to join the round. Pull the magic ring tail to close the center tightly.

You now have 12 dc in a circle.

Round 2: Doubling Up

This round doubles your stitch count, expanding the sunburst.

1. Ch 3 (counts as dc). Work 1 dc in the same stitch (this is your increase).
2. Work 2 dc in each dc around the circle.
3. Sl st to the top of the ch-3 to join. You should have 24 dc.
4. Fasten off color A and weave in the end.

Round 3: Adding Warmth

Time to introduce color B (Burnt Orange) for a beautiful gradient effect.

1. Join color B in any dc from the previous round.
2. Ch 3 (counts as dc). Work 1 dc in the same stitch (increase made).
3. *Dc in the next dc, then 2 dc in the following dc.*
4. Repeat from * to * around the circle.
5. Sl st to join. You should have 36 dc. Fasten off color B.

Round 4: Deepening the Palette

Now we bring in color C (Deep Magenta) to add richness and depth.

1. Join color C in any dc.
2. Ch 3 (counts as dc). Work 1 dc in the same stitch.
3. *Dc in the next 2 dc, then 2 dc in the following dc.*
4. Repeat from * to * around.
5. Sl st to join. You should have 48 dc. Fasten off color C.

Round 5: The Teal Transition

Color D (Teal) brings a cool, calming contrast to the warm center.

1. Join color D in any dc.
2. Ch 3 (counts as dc). Work 1 dc in the same stitch.
3. *Dc in the next 3 dc, then 2 dc in the following dc.*
4. Repeat from * to * around.
5. Sl st to join. You should have 60 dc. Fasten off color D.

Round 6: Creating the Square Corners

This is where the circle becomes a square! We'll use color E (Cream) to create the corners and straight sides.

1. Join color E in any dc.
2. Ch 3 (counts as dc). Work 1 dc in the same stitch.
3. *Dc in the next 14 dc. Then, in the next dc, work (2 dc, ch 2, 2 dc) – this creates your corner.*
4. Repeat from * to * 3 more times. On the last repeat, after the corner, work dc in the next 14 dc.
5. Finally, work 2 dc in the starting dc (the one where you joined), ch 2, and sl st to the top of the ch-3 to join.

Each side of your square now has 18 dc, with ch-2 spaces at each corner. Fasten off color E and weave in all ends. Repeat this entire process to make 16 beautiful squares!

Joining Your Squares

Now for the magic – assembling your mosaic! This flat joining method creates a beautiful, seamless grid.

1. Arrange: Lay out your 16 squares in a 4x4 grid. For a dynamic mosaic effect, alternate the starting color positions. For example, rotate some squares so the yellow centers are in different corners, creating a more organic, stained-glass look.
2. Join Vertically: With color E, use the flat slip stitch join method on the wrong side of the work. This means you'll hold two squares with their right sides together and slip stitch through the back loops of both edges. Start by joining the vertical seams first – connect all squares in each column.
3. Join Horizontally: Once your vertical seams are done, work the horizontal seams. Ensure all corners align perfectly for a crisp, professional finish.

Adding the Border

The border frames your masterpiece and gives it a polished, finished look.

Border Round 1

1. With color E, join your yarn in any corner ch-2 space of the assembled blanket.
2. Ch 3 (counts as dc). Work (dc, ch 2, 2 dc) in the same corner space.
3. *Dc in each dc across to the next corner. Then work (2 dc, ch 2, 2 dc) in the corner space.*
4. Repeat from * to * around the entire blanket.
5. Sl st to join.

Border Round 2

1. Ch 3 (counts as dc).
2. Dc in each dc around the blanket. When you reach a corner ch-2 space, work (2 dc, ch 2, 2 dc) in that space.
3. Sl st to join. Fasten off and weave in all ends securely.
