Factors to consider when choosing merino wool aran

• Fiber: 100% merino, or a blend. Some brands also say mulesing-free.
• Treatment: superwash or not.
• Yardage: yards per skein vary a lot between brands. Buy by yards, not skein count.
• Gauge: most merino aran knits at about 4 to 5 stitches per inch on US 7-9 (4.5-5.5mm) needles. Match it to your pattern.
• Dye lot: buy all your skeins from one lot.

What Merino Wool Aran Is

Merino is a breed of sheep with very fine wool. The fine fibers feel soft next to the skin, with far less itch than coarser wools. That is why merino is a favorite for hats and sweaters.

Aran is the yarn weight. It sits at the heavy end of the medium group, a little thicker than worsted. Our aran weight yarn guide explains the weight and gauge in full, with needle sizes.

Put the two together and you get a soft yarn that knits up quickly into warm, cushy fabric.

Superwash vs. Non-Superwash Merino Wool Aran

Most merino wool aran yarns on the shelf are superwash. Superwash wool is treated so the fibers do not felt. You can machine wash it on a wool or gentle cycle.

Superwash has tradeoffs. It can grow a little when wet, and it has less spring than untreated wool. Cables can look slightly softer.

Non-superwash merino keeps its natural bounce and blocks into crisp shapes. It must be hand washed, or it will felt. Choose it for a special cabled sweater you are happy to wash by hand.

What Merino Wool Aran Knits Best

• Cabled sweaters: the classic use. See our cable stitch sweater guide.
• Hats, cowls and mittens: soft enough to wear next to the skin.
• Baby and kids' clothes: a superwash merino survives frequent washing.
• Blankets: warm and soft, though a large one uses a lot of yarn.

Merino is soft but can pill where it rubs, like underarms and cuffs. A tightly plied merino pills less than a loose single. If a finished piece does pill, a fabric shaver or sweater comb lifts the small balls off without harming the knit.

Compare swatches before a big project. Two merino aran yarns from different brands can feel quite different, from dense and smooth to light and lofty. That changes both drape and warmth.

Merino Wool Aran FAQ

Is merino wool aran itchy?

Most people find merino much softer than regular wool. Very sensitive skin may still notice it, so try a skein first.

Can merino wool aran go in the washing machine?

Only if it is superwash. Check the label. Non-superwash merino needs a gentle hand wash.

What needles do I use for merino wool aran?

Usually US 7-9 (4.5-5.5mm). Swatch to match your pattern's gauge.

Verdict on Merino Wool Aran

A superwash merino wool aran is the easy-care choice for sweaters and kids' clothes. Choose a non-superwash merino wool aran when you want crisp, springy cables and do not mind hand washing. Either way, check yardage and gauge, and buy one dye lot for the whole project.
