Washing a wool swatch is a simple yet crucial step to understand how your yarn will behave after finishing, particularly regarding gauge, drape, and color fastness.
To wash a wool swatch effectively and gently, follow these steps which are based on recommended practices for handling wool fibers and setting dyes.
## Step-by-Step Guide to Washing Your Wool Swatch
Proper washing involves soaking and gentle handling. Here's a breakdown:
1. **Prepare the Basin:** Fill a basin with **cold water**. This helps prevent felting, which can occur with sudden temperature changes or hot water.
2. **Add Additive:** To the cold water, add **0.5 to 1 cup of white vinegar** or drop in a **dye catcher sheet**. White vinegar can help set some types of dye (especially acid dyes commonly used on wool) and prevent color bleeding. A dye catcher sheet will absorb any loose dye released from the yarn.
3. **Soak the Swatch:** Submerge your wool swatch (or your yarn if testing the skein) completely in the prepared water.
4. **Soak Time:** Let the swatch **soak** for a maximum of **30 minutes**. Avoid leaving it in for too long, especially if significant bleeding is occurring.
5. **Rinse Gently:** After soaking, gently **rinse** the swatch in **cold water**. Avoid wringing or twisting, which can damage the fibers and cause felting. You may need to rinse several times until the water runs clear, especially if using vinegar.
6. **Block and Dry:** **Block** your swatch by laying it flat on a towel or your blocking mats. Gently shape it to your desired dimensions. If testing yarn, lay it out flat. Allow the swatch to **dry** completely.
## Why Wash Your Swatch?
Washing a swatch is essential because:
* **Gauge Check:** It shows you the true size and shape of your stitches *after* washing and drying, which is the final state of your project. This helps you confirm or adjust your needle/hook size.
* **Drape Assessment:** You can see how the fabric will drape and feel once finished.
* **Color Fastness:** It reveals if the yarn's dye is stable and if it will bleed onto other colors or surfaces.
