Semilla Grosso is suitable for knit and crochet projects. We’ve included gauge suggestions for these crafts below. You may also like to check out our project suggestions on RAVELRY.

This yarn is spun with an intended soft and squishy hand-feel. This is achieved by using a fine staple fibre and milling with a looser twist, both elements that can contribute to pilling. We recommend working the yarn at the firmer end of the gauge spectrum to reduce pilling. 

The colours used to dye this yarn are produced according to GOTS standards, this includes restrictions on certain chemicals that aid light-fastness.In exceptional cases, placing yarn or projects in direct sunlight for extended periods of time may affect light-fastness.


The gauge information below can be used as guidance when planning your projects. We always recommend that you swatch to determine a configuration that results in the ideal fabric and hand feel for your project.


14-18 stitches over 10cm, using 4.5 - 5.5mm needles (3.5 – 4.5 stitches per inch, US size 7-9 needles)


11-14 stitches over 10cm, 5.5mm - 6mm hook (2.75-3.5 stitches per inch, US size I–9 to K–10 ½ hook)


The true texture and appearance of the yarn remains hidden until a final wash fluffs and softens the fibres.

To block or wash your piece, prepare a bath of tepid water and if desired add a few drops of mild detergent or wool wash. Immerse the piece and soak for 10 to 15 minutes. Lift the piece from the water and allow to drain. Gently remove excess water by pressing the fabric between layers of a dry towel. Lay flat to dry.
