How to block knitwear properly: A step-by-step guide
Blocking is an essential technique in knitting that helps you achieve the perfect fit, shape, and finish for your projects. Whether you're knitting a sweater, scarf, or shawl, blocking helps relax the fibers, smooth out any wrinkles, and ensure your piece holds its intended shape. The method you choose will depend on the type of yarn used, the complexity of your design, and your desired results. In this guide, we’ll cover the three most common blocking methods: wet blocking, steam blocking, and spray blocking.
WET BLOCKING: The most common and effective method
Wet blocking is one of the most widely used and effective methods, especially for larger projects like sweaters or blankets. This method allows you to fully saturate your knitted piece with water, helping to reshape and relax the fibers.
Steps for wet blocking:
- Soak your knitwear: Begin by soaking your knitted piece in cool water with a gentle wool wash or mild detergent. Ensure the entire piece is submerged and let it soak for about 15-20 minutes.
- Remove excess water: After soaking, gently squeeze out excess water by pressing the piece, but avoid wringing, as this can distort the fabric.
- Shape and pin: Lay the item flat on a towel or blocking mat. Gently stretch and shape it to the correct dimensions, making sure to align the edges and seams. Use rust-proof pins to pin the project into place, holding it in the desired shape.
- Dry: Allow your piece to dry completely before removing the pins. This can take anywhere from a few hours to a day, depending on the size of your project and the humidity level in your environment.
Benefits of wet blocking:
- Ideal for most yarn types, including wool, cotton, and acrylic.
- Provides the most thorough and even reshaping of your project.
- Sets stitch definition, especially for lace and textured designs.
STEAM BLOCKING: Perfect for delicate yarns and smaller projects
Steam blocking is a great method for delicate yarns, such as silk or alpaca, that may be prone to stretching. This technique uses the heat and moisture from steam to relax the fibers without saturating the fabric.
Steps for steam blocking:
- Prepare the steam iron: Set your steam iron to the "steam" setting, making sure it’s at a low heat to prevent damage to the fibers.
- Steam from above: Hold the steam iron several inches above your knitted piece. Allow the steam to penetrate the fabric, gently relaxing the stitches. Avoid placing the iron directly on the project to prevent scorching or flattening the fabric.
- Shape and pin: Once the piece is steamed, carefully pin it into shape on a blocking mat or towel, using pins to hold the edges in place.
- Let it cool: Allow your piece to cool and set into its final shape. The steam will help the fabric hold its structure without the need for prolonged drying time.
Benefits of steam blocking:
- Works well for delicate yarns and smaller projects.
- Helps prevent over-stretching while relaxing fibers.
- Quicker than wet blocking, as there’s no soaking or long drying process.
SPRAY BLOCKING: Quick and convenient for small projects
Spray blocking is the perfect solution for smaller projects, such as socks, mittens, or lace shawls. This method is fast, effective, and doesn't require soaking or excessive moisture.
Steps for spray blocking
- Mist your project: Lightly spray your knitted piece with water using a spray bottle. Be careful not to saturate the fabric—just dampen it enough to relax the fibers.
- Pin to shape: Pin the dampened piece into the desired shape on a blocking mat or towel. Ensure the edges are straight and the fabric is even.
- Dry: Allow the piece to dry completely while pinned in place. Spray blocking works best for lightweight fabrics or yarns that don’t need a lot of reshaping.
Benefits of spray blocking:
- Quick and easy, ideal for small projects.
- Works well for projects made with non-stretchy yarns or when only minor adjustments are needed.
- No need for long drying times or soaking.
Which blocking method should you choose?
The blocking method you select depends on your project’s size, the yarn type, and how much time you have available. Here's a quick breakdown:
- Wet blocking: Best for large projects like sweaters, blankets, and shawls made from natural fibers like wool or cotton. Ideal for setting lace and textured patterns.
- Steam blocking: Suitable for delicate fibers or smaller projects that need gentle shaping without soaking.
- Spray blocking: Great for smaller projects, like socks or scarves, when you’re short on time or just need light reshaping.
Blocking is a simple yet essential technique that can make a world of difference in the appearance and fit of your knitted items. Whether you choose wet blocking, steam blocking, or spray blocking, this step ensures your projects will look their best, with smooth, well-defined stitches, a perfect shape, and a beautifully finished texture. By investing time in blocking, you’ll create knitwear that not only fits perfectly but also stands out with professional-quality results.
