About The Yarn

Flat lay of yarn including green, pink, cream, and off-white balls of Bella Coco Merino yarn. Half in a circular rattan tray and the others stacked neatly on a pale pink background with eucalyptus leaves at the top of the image.

Bella Coco Merino is spun with a z-twist instead of the classic s-twist. This special twist means that this yarn is made specifically for crocheters. Where the s-twist may tend to split and unwind when you work with it, the z-twist keeps the structure intact. The result is a smooth, flexible, and comfortable crafting experience! Available in 30 shades and 5 prints, this carefully curated colour palette includes: delicate pastels and muted shades to bright middle tones and vivid colours which can be mixed and matched to your creative heart’s content!

Customisation

Bodies come in all shapes and sizes, so you may find that you want to adjust your sizing to suit your own body or your own taste.

Sleeve length

If you decide that you want your sleeves longer, you can add another row of squares to the length. This can be done at any time prior to adding the ribbing. If you have already connected your squares using the join as you go method, simply make another smaller panel and add on to the bottom of the sleeve.

Length

Similarly to the sleeves, if you decide that you would like your cardigan a little (or a lot) longer, you can add a row or more of squares to the base of the work providing its done before the bottom ribbing.
