What Are Arm Warmers?

Arm warmers and wrist warmers are made to keep your hands warm when you are typing or driving.

Made like sleeves without the rest of the sweater, these are designed to keep your hands warm on a chilly day while at the same time comfortable.

Originally worn mostly by dancers to warm their arms up during practice, they are great for keeping your arms warm without wearing a bulky sweater.

They are also great for gift-giving as they knit up quickly.

Everything You Need To Know About Knitting Arm Warmers

How many stitches do you cast on for arm warmers?    

The number of stitches you cast on for arm warmers will depend on several factors, including the size of the arm warmers, the yarn weight, and your own gauge.

To get a customized fit, you may need to measure your wrist and forearm circumference and make a gauge swatch.

Here’s a general guideline to help you determine the number of stitches for arm warmers:

Measurements: Measure the circumference of your wrist and the widest part of your forearm (usually just below the elbow). Additionally, measure the length from your wrist to the desired length of the arm warmer.

Gauge Swatch: Make a gauge swatch using the yarn and the crochet hook or knitting needles you plan to use for the arm warmers. Measure the number of stitches per inch or centimeter to determine your gauge.

Calculate Stitches: Once you have your gauge, multiply the stitches per inch or centimeter by the desired circumference for the wrist and forearm. This will give you an estimate of the number of stitches needed.

Adjust for Ribbing (Optional): If you plan to add ribbing to the arm warmers, you may need to adjust the number of stitches. Ribbing is often worked with a smaller needle or hook size to ensure a snug fit.

Consider Pattern: If you’re following a specific pattern for arm warmers, check the pattern for any recommendations on the number of stitches to cast on.

How much yarn is needed for arm warmers?   

The amount of yarn needed for a pair of arm warmers can vary based on factors such as the yarn weight, stitch pattern, arm warmer size, and your individual tension.

However, I can provide you with a rough estimate based on some common scenarios:

  1. Lightweight Yarn (Fingering or Sport Weight):
    • For a pair of simple, mid-length arm warmers (wrist to mid-forearm), you might need approximately 200 to 300 yards (183 to 274 meters) of lightweight yarn.
  2. Medium Weight Yarn (Worsted Weight):
    • If you’re using a medium-weight yarn for standard-length arm warmers, you might require around 150 to 250 yards (137 to 229 meters) of yarn.
  3. Chunky or Bulky Yarn:
    • Arm warmers made with chunky or bulky yarn will likely need less total yardage. You might estimate around 100 to 200 yards (91 to 183 meters) for a pair.

These estimates are based on the assumption that you’re making a standard pair of arm warmers without a particularly elaborate stitch pattern or extra length.

If you plan to incorporate textured stitches, cables, or other design elements, you may need more yarn. 

Additionally, if you’re making longer arm warmers or have a larger arm circumference, you’ll require more yarn.

The easiest way to knit this pair of hand warmers is by using straight needles.

Both pieces are identical, so you just repeat the pattern for the second warmer.

You start by following the pattern to create a rectangle, which is then seamed together.

The Yarn I Used To Knit The Wrist Warmers

I knit the wrist warmers you can see in the photo below with medium-weight yarn (aran to worsted weight yarn) (04), in Cascade 220 in Lavender Heather 2422 and Drops Kid-Silk- Lavender 11.

I knit two strands together to give them some texture, and they turned out soft and fuzzy.

You will create ridges using knit and purl stitches, then continue to knit in stockinette stitch on straight needles.
