Elevate your handmade wardrobe with the elegant
and eye-catching Seaglass Mosaic Cardigan — a truly unique
piece that blends timeless style with modern crochet
techniques.

Designed using inset mosaic crochet, this pattern
delivers stunning colourwork without the hassle of
weaving in tails or carrying yarn, making it both
beginner-friendly and rewarding to create.
Crafted in the luxuriously soft Bella Coco Merino
Wool, the Seaglass Cardigan showcases a beautiful,
gradual teal blue print that adds depth and
dimension to every stitch. The yarn’s gentle drape
complements the cardigan’s chic cropped length,
relaxed sleeves, and snug cuffs, creating a silhouette
that’s both flattering and comfortable.

construction details.

Size Chart & Yarn Requirements

Please note that this design is a classic fit with positive ease. When selecting your size, refer to your preferred Finished Bust Measurement. Size up or down as needed for desired fit. Due to the pattern repeat some sizes are combined. For reference, the model is wearing a medium with a 36″ bust and is 5 feet 6 inches tall.
Please note that yarn amounts are estimates and may vary slightly between different yarn brands and individual tension. It’s always a good idea to have a little extra yarn on hand to avoid running out during your project. Happy crocheting!

Skill Level
Mosaic crochet knowledge is recommended for the Seaglass Cardigan crochet pattern.
Gauge


Suitable Yarn Substitutes for Bella Cocoa Merino
If your gauge is off, try adjusting your crochet hook size or even switching the hook style or brand. Keep in mind that not all yarn weights are exactly the same, even when labelled identically; differences in thickness, drape, and softness can occur.
For this pattern, I recommend crocheting the mosaic section with a 4mm hook, following the chart and directions on page 10 of the PDF pattern. Measure your stitches at the centre of the swatch. If you have too many stitches, move up to a larger hook size; if you have too few, switch to a smaller hook. You can also fine-tune stitch height with your technique — lengthen stitches by pulling up slightly, or shorten them by tightening your tension.
