Lana para tejer un jersey de otoño

What wool to use to knit a fall sweater 🍂

Fall is the perfect season to debut a new hand-knitted sweater. The days are getting cooler, and we need warmer clothes, but we're not yet looking for the thickest winter yarns. If you're thinking of knitting a fall sweater, choosing the right yarn is key to achieving a comfortable, warm, and durable garment.

In this article, we'll tell you the best options in terms of thickness, composition, and colors , with examples of skeins you can find in our Idealium store.


1. Recommended thickness for autumn

For a mid-season sweater, it is ideal to work with DK (Double Knitting), Sport or even light Worsted weight yarns.

  • Sport (2.5 – 3.5 mm needle) : for thinner, breathable jerseys, perfect for wearing with T-shirts underneath.
  • DK (3.5–4.5 mm needle) : The most versatile weight for autumn; it allows for lightweight yet full-bodied garments.
  • Light worsted (4.5 – 5 mm needle) : provides more warmth, ideal for cold November days.

2. Composition: wool, cotton or blends

The wool composition will influence the warmth, breathability, and softness of your sweater. These are the most recommended options for fall:

  • Premium acrylic : lightweight, soft, and easy to care for. Ideal for everyday use and frequently washed garments. Example: Rubi Campiña Yarn , an acrylic for lightweight garments.
  • Merino wool : Provides warmth and softness without being heavy. Perfect for cozy sweaters. Example: Idealium Merino Luxe , a 100% merino wool.
  • Cotton blend : For those who don't tolerate wool well or prefer a cooler feel. In autumn, it's used in combination with acrylic or viscose to add body. Example: Rubi Bruma Ball , a cotton and viscose fiber with a light, shiny finish.
  • Mohair and silk/acrylic blends : These provide a lightweight, airy, and warm finish. A stylish option if you're looking for a sweater with a fluffy texture. Example: Idealium Etherea, a wool and mohair blend with a soft, fluffy finish.

3. Trendy shades for autumn 🍁

Color is as important as the fiber. In autumn, warm, natural tones that evoke the season are popular:

  • Earth tones : ochre, camel, beige, soft browns.
  • Reddish and burgundy : intense colors that combine with jeans and basics.
  • Olive and forest greens : very trendy this year.
  • Timeless neutrals : light grey, pearl and off-white, perfect for basic sweaters.

4. Final tips for choosing your fall wool

  • If you are a beginner : choose an acrylic ball like Rubi Campiña ; it doesn't deform and is very easy to practice on.
