What is Blocking in Knitting and How is it Done?

Blocking is an essential step in knitting that enhances the final appearance and shape of your knitted projects. Whether you're working on scarves, sweaters, or intricate lacework, blocking helps even out stitches, define patterns, and give your work a professional finish. But what exactly is blocking, and how is it done?

What is Blocking in Knitting?

Blocking is the process of wetting or steaming your finished knitted piece and then shaping it to the desired dimensions. This helps relax the fibers, allowing your stitches to open up and settle evenly. It also gives your project a smoother and more polished look by removing any curling or uneven tension in the fabric. Blocking is especially important for lace patterns, where the intricate details often need to be opened up for full visibility.

Types of Blocking Methods

There are three main methods of blocking that knitters commonly use:

1. Wet Blocking: This is the most common method. You submerge your knitted piece in water, gently squeeze out excess moisture, and then pin it to the desired shape on a flat surface, like a blocking mat. Leave it to air dry completely.

2. Steam Blocking: Using a steam iron or steamer, this method allows you to block without fully wetting the fabric. Hold the steamer or iron a few inches away from the piece and allow the steam to relax the fibers. Gently shape and pin the piece as needed.

3. Spray Blocking: Similar to wet blocking, but instead of soaking the entire piece, you lightly spray it with water, then pin and shape it to dry. This method works well for more delicate yarns that don’t need heavy blocking.

How to Block a Knitted Project – Step by Step

Here’s a simple guide to blocking your knitted piece using the wet blocking method:

1. Soak Your Knitting: Fill a basin or sink with lukewarm water. Submerge your knitted project and let it soak for about 20-30 minutes. You can add a gentle wool wash if desired, but it’s not necessary.    

2. Remove Excess Water: After soaking, gently lift your project out of the water and press it against the side of the sink or basin to remove excess water. Be careful not to wring or twist it, as this can damage the fibers.

3. Prepare the Blocking Surface: Lay out a blocking mat, foam board, or a clean towel on a flat surface. Place your knitted piece on it and start shaping it to the desired dimensions. Pin the edges with rust-proof pins, making sure everything is symmetrical and evenly stretched.

4. Let it Dry: Allow your project to air dry completely. Depending on the yarn and the size of the project, this can take anywhere from a few hours to a full day.

Benefits of Blocking

• Evens Out Stitches: Blocking helps smooth out uneven stitches, making your project look neater and more uniform.
• Enhances Patterns: For lace and cable knits, blocking helps open up intricate designs, allowing the details to be more visible and defined.
• Improves Fit: For garments, blocking can help achieve the perfect fit by shaping the fabric to specific dimensions.
• Prevents Curling: Some types of stitches, like stockinette, tend to curl. Blocking helps flatten these edges for a polished finish.

When to Block

Blocking is typically done after completing a knitting project, but you can also block pieces before seaming them together, especially for garments. It’s important to check the yarn label for blocking recommendations, as some fibers (like acrylic) may not respond well to traditional blocking methods.

Conclusion

Blocking is a vital step in knitting that can transform your project from good to great. By relaxing the fibers and shaping your work, you’ll achieve a more refined and professional look. Whether you're working on a delicate lace shawl or a cozy sweater, don't skip this important final touch!
