Yarn Care Guide

Reading the Care Symbols on a Yarn Label

Most yarn ball bands use the same international care symbols you see on clothing tags. These five shapes cover nearly every label:

Symbol	What it means
Washtub	Machine washable. Dots inside show the hottest water allowed: one dot is cold (30°C / 86°F), two dots is warm (40°C / 104°F), three dots is hot (50°C / 122°F). A line under the tub means a permanent-press cycle; two lines means the gentle or delicate cycle.
Washtub with a hand	Hand wash only, in cool to lukewarm water.
Washtub with an X	Do not wash in water. Usually paired with a dry-clean symbol.
Triangle	Bleach. An empty triangle means any bleach is fine, a triangle with two diagonal lines means non-chlorine bleach only, and a crossed-out triangle means no bleach at all.
Square with a circle inside	Tumble dry. Dots show the heat setting (one dot is low). Crossed out means never put it in the dryer.
Square with one horizontal line	Dry flat. This is the right choice for most handmade pieces.
Square with a curved line at the top	Line dry (hang to dry). Avoid this for heavy knits and crochet, since hanging stretches them.
Iron	Ironing. Dots show the heat level; crossed out means no ironing.
Circle	Dry clean. A letter inside tells the dry cleaner which solvent to use; crossed out means do not dry clean.

The label tells you what the yarn can handle, not what your finished project needs. A machine-washable yarn made into a heavy blanket may still come out better washed on gentle and dried flat, because the weight of wet fabric is what pulls a project out of shape.

Why Fiber Matters More Than Anything Else

Each fiber fails in its own way, and knowing how it fails tells you what to avoid. Wool and alpaca felt: heat plus agitation locks their fibers together permanently and shrinks the piece. Cotton, bamboo, and alpaca grow: they are heavy and have little elasticity, so they stretch when wet or hung. Acrylic can be "killed": high heat from a hot dryer or iron relaxes it permanently, leaving it limp and shiny. Every instruction above is built around avoiding the specific failure your fiber is prone to.

How to Wash a Crochet or Knit Project

You put hours into a handmade piece, and one wrong wash can undo it. The good news is that washing handmade items safely comes down to a few habits: gentle handling, no temperature shocks, and drying flat. Here's the process from start to finish.

Step 1: Check the yarn label

If you still have a ball band, it is the best source of truth for your yarn. Look for the washtub symbol and any dots or lines with it. If you no longer have the label, use the fiber picker above, and when in doubt, treat the piece as hand wash only. You can't go wrong with that.

Step 2: Fill a basin with cool or lukewarm water

Use a clean sink, bathtub, or large bowl. Lukewarm, about the temperature of a baby's bath, is right for nearly everything. Hot water risks felting wool and can shrink cotton, and the bigger danger with wool is a sudden change in temperature. Use the same temperature water for washing and rinsing.

Step 3: Add a gentle detergent

Use a wool wash or a small amount of mild, dye-free detergent. No-rinse wool washes are especially convenient: you soak the piece and skip rinsing entirely, which means less handling. Avoid regular laundry detergents with enzymes on wool, alpaca, and silk, since enzymes break down protein fibers over time. Skip fabric softener on all fibers; it coats the yarn and can make acrylic feel greasy.

Step 4: Soak, don't scrub

Lay the piece in the water and gently press it down until it's fully soaked. Let it sit for 15 to 20 minutes. Resist the urge to swish, rub, or wring it; agitation is what turns a wool sweater into felt. For a spot that needs extra attention, gently squeeze the soapy water through that area a few times.

Step 5: Rinse if your detergent needs it

If you used a regular mild detergent, drain the basin and refill it with clean water at the same temperature. Press the piece gently to rinse, then drain again. Repeat until the water runs clear. With a no-rinse wool wash, skip this step.

Step 6: Press out the water

Never lift a soaking-wet project by one corner or hold it up by the shoulders. Wet yarn is heavy and will stretch under its own weight. Instead, push the piece to one side of the basin and press out as much water as you can. Then scoop it up in both hands, supporting the whole thing.

Step 7: Roll it in a towel

Lay the piece flat on a large, dry towel. Roll the towel up with the project inside, like a sleeping bag, and press or kneel on the roll to squeeze water into the towel. For a big blanket, use two or three towels. Some makers also use the washing machine's spin-only cycle for this step, which removes even more water with no agitation. Just make sure it's set to spin only, with no wash or rinse.

Step 8: Dry flat and shape it

Unroll the piece and lay it flat on a dry towel, blocking mats, or a mesh drying rack, out of direct sunlight and away from heaters. Gently pat it into shape and size: straighten edges, line up seams, and smooth any ripples. This is a light re-blocking every time you wash. Flip it over after several hours so both sides dry evenly. Thick projects can take a day or two to dry completely, so don't fold or store them while they're still damp.

Machine Washing Safely

Acrylic, cotton, linen, and most superwash wools can go in the washing machine, and doing it carefully keeps them looking new much longer:

Do	Why
Put the piece in a mesh laundry bag	Prevents snagging and stops stitches from catching on the drum or other clothes.
Use the gentle or delicate cycle	Less agitation means less pilling, fuzzing, and stretching.
Choose cold or warm water, never hot	Hot water fades colors, shrinks cotton, and can damage acrylic.
Wash with similar colors	Hand-dyed and bright yarns, especially reds, can bleed in the first few washes.
Skip the dryer unless you're sure	Only acrylic, cotton, and linen tolerate tumble drying, and only on low. Flat drying is always the safe choice.

Storing Handmade Pieces

Always wash before storing anything for the season. Moths and carpet beetles are drawn to body oils and food traces as much as to wool itself. Fold knits and crochet rather than hanging them, since hangers stretch shoulders and leave bumps. Store pieces in breathable cotton bags or bins with a cedar block or lavender sachet. Avoid sealed plastic for long periods, which can trap moisture.

Fixing Common Washing Problems

Problem	What happened and what to do
Wool sweater shrank and feels thick	It felted from heat and agitation. Felting can't be fully reversed, but soaking in lukewarm water with a generous squirt of hair conditioner for 30 minutes, then gently stretching it back toward size while damp, can recover some of it.
Project grew longer after washing	Heavy, low-elasticity fibers like cotton, bamboo, alpaca, and superwash wool stretch when wet. Re-wet it, press out the water, and dry it flat, pushing it back to the right size. Never hang these fibers.
Acrylic went limp and shiny	Too much heat "killed" it. This is permanent, but it often makes the fabric drapier, which some makers do on purpose for shawls.
Fuzz balls (pilling)	Normal friction, especially on soft or loosely spun yarns. Remove them gently with a sweater comb or fabric shaver.
Colors bled onto lighter yarn	Rewash right away in cool water with a color-catcher sheet, before the piece dries. Next time, soak bright yarn alone first to check for bleeding.
