Blue Lagoon Throw in Caron One Pound – Crochet Pattern Summary

About This Pattern

The Blue Lagoon Throw is a free, downloadable crochet pattern designed by Margret Willson and worked in Caron One Pound yarn. It produces a striking, large-scale afghan featuring unique circular motifs set within square blocks, rendered in a rich palette of bold blues, greens, and violets. The finished throw is sized generously for home décor use, measuring 45 inches wide by 60 inches long (114 cm × 152.5 cm), making it ideal as a sofa throw, lap blanket, or decorative accent piece.

Design Overview

The design is built from 35 individual granny-style square blocks, each measuring approximately 8 inches (20.5 cm) square. Each block begins with a small foundation ring and is worked outward in rounds, creating a circular motif at the center that radiates into a structured square shape. The blocks are worked with the right side facing throughout, which helps maintain consistent stitch definition and a clean, professional finish on the public-facing side. Once all 35 blocks are completed, they are assembled to form the full throw.

Color Palette

One of the most distinctive features of the Blue Lagoon Throw is its multi-color construction using six contrast shades of Caron One Pound:

• Contrast A – Midnight Blue (0546)
• Contrast B – Soft Sage (0580)
• Contrast C – referenced in the pattern materials list
• Contrast D – Deep Violet (0547)
• Contrast E – Royalty (0530)
• Contrast F – Forest Green (0534)

This combination of deep jewel tones and cool sage greens gives the throw its lagoon-inspired aesthetic, evoking depth, water, and lush natural scenery. The interplay of these shades across the circular motifs creates a visually dynamic, cohesive result that works beautifully in a variety of home décor settings.

Techniques Used

The Blue Lagoon Throw is rated as a beginner-level crochet project, making it an excellent choice for those who are comfortable with basic crochet stitches and ready to explore simple motif construction. The primary technique involves working in the round from a central chain ring, a foundational skill in crochet that produces circular and square motifs. Each block starts with a chain-4 ring joined with a slip stitch, then grows outward round by round. Working with multiple yarn colors across the blocks introduces simple color management, which is great practice for newer crocheters looking to build confidence.

Stitches Used

The pattern draws on a small, accessible set of standard crochet stitches:

• Chain stitch (ch) – used to form the foundation ring and turning chains
• Slip stitch (sl st) – used to join rounds and close the foundation ring
• Single crochet (sc) – a short, tight stitch used for structure and joining
• Half double crochet (hdc) – a mid-height stitch adding texture and body
• Double crochet (dc) – the primary stitch used throughout the blocks, including as the first stitch of Round 1 (worked as a chain-3 turning chain)
• Treble crochet (tr) – a taller stitch used for decorative effect within the motif rounds

The combination of these stitches at varying heights creates the dimensional, circular appearance of each motif, giving the finished throw its characteristic texture and visual interest.
