  4. Round 4: Chain 3, dc in the next 2 stitches, then 2 dc in the next stitch. Now, *dc in the next 3 stitches, 2 dc in the next stitch; repeat from * around. Join with a sl st. You will have 48 dc.
  5. Round 5: Change to deep navy yarn. Chain 3, dc in the next 3 stitches, then 2 dc in the next stitch. Now, *dc in the next 4 stitches, 2 dc in the next stitch; repeat from * around. Join with a sl st. You will have 60 dc.
  6. Round 6: Chain 3, dc in the next 4 stitches, then 2 dc in the next stitch. Now, *dc in the next 5 stitches, 2 dc in the next stitch; repeat from * around. Join with a sl st. You will have 72 dc.
  7. Round 7: Change to sky blue yarn. Chain 3, dc in the next 5 stitches, then 2 dc in the next stitch. Now, *dc in the next 6 stitches, 2 dc in the next stitch; repeat from * around. Join with a sl st. You will have 84 dc.
  8. Rounds 8-20: Continue following the increasing pattern established in the previous rounds, changing colors every 3 rounds to create a gradient effect. End with deep navy yarn.
  9. Round 21: Using seafoam yarn, chain 3, then *dc in each stitch around. Join with a sl st. (No increases this round.)
  10. Rounds 22-25: Repeat Round 21, alternating colors for a border effect. This will give your blanket a finished look.
  11. Finishing: Once you have completed the final round, finish off your work by cutting the yarn, leaving a tail. Weave in all ends using a yarn needle to ensure a clean finish.

The finished blanket will be a large, circular afghan with a diameter of approximately 60 inches, showcasing a beautiful gradient of cool ocean blues. Enjoy the cozy yet elegant cottagecore aesthetic of your new Ocean Bloom Blanket!
