What Does Blocking Mean in Knitting?

When you’ve completed your knitting project, it may not yet have the smooth, professional look you desire. That’s where blocking comes in.

Blocking your knitting is a simple yet essential technique. It involves shaping and setting the final size and form of your finished knitted piece.

By dampening and then gently stretching the knitted fabric, you can achieve a polished and uniform appearance. This process helps to even out stitches and any inconsistencies in the knitting, open up lace patterns, and give your project that extra finesse.

Whether you’re making a cozy sweater, a delicate beanie, or warm socks, blocking can make a significant difference in the final outcome. It’s like giving your knitting a spa treatment—it relaxes the fibers and helps them settle into their intended shape.

In other words, blocking knitting is an essential part of the knitting process that can take your creations from basic to beautiful. Whether you’re a seasoned knitter or just starting out, mastering the art of blocking will take your handmade creations to the next level.

Why Blocking Your Knitting Matters?

After spending all that time knitting your project, you want it to look and feel its best. Blocking your knitting can help achieve this by evening out tension, smoothing out uneven stitches, and even hiding minor imperfections or mistakes.

Blocking also helps shape the knitted fabric to its intended dimensions, ensuring that garments, such as socks, mittens, and sweaters, fit comfortably and accurately according to the pattern’s specifications.

Additionally, blocking can enhance the stitch definition and bring out intricate patterns or textures. This is especially important for lace or cable designs, where blocking can make the details pop.

Furthermore, blocking knitting is not just about aesthetics; it’s also about ensuring the longevity of your handmade garments. By setting the stitches and shaping the fabric, blocking helps prevent the garment from stretching out of shape over time. This means it will maintain its fit and structure, even after repeated wear and washing.

Whether you’re knitting for yourself or a gift for someone else, taking the time to block the knitted piece can make a world of difference. Overall, blocking your knitted piece matters because it can significantly improve the fit, appearance, and durability of the finished product.

How to Block Knitting

There are couple of different methods for how to block knitting, each with its own advantages and suitability for different types of projects.

Wet Blocking: This method involves soaking the knitted item in water, gently squeezing out excess moisture, and then shaping it to the desired dimensions before allowing it to air dry.

Steam Blocking: Steam blocking involves using steam from an iron or garment steamer to relax the fibers and shape the knitted piece. It’s particularly useful for projects made from natural fibers like wool.

Spray Blocking: In spray blocking, you mist the knitted item with water using a spray bottle, then shape it and allow it to dry. This method is convenient for smaller projects or items with delicate fibers.

Combination Blocking: Some knitters use a combination of wet blocking and steam blocking techniques for optimal results, especially for projects with complex stitch patterns or lacework.

Ultimately, the method you choose depends on the fiber content of your project, the desired outcome, and—first and foremost—personal preference. Experimenting with different blocking techniques can help you find the one that works best for your knitting projects.

I personally prefer wet blocking my knitted pieces, so I will be providing instructions for that method in this post.

Tools Needed for Blocking Knitting

To effectively block knitting, you’ll need a few essential tools:

  • Blocking Mats or Towels: These provide a flat surface for shaping your knitted piece and protect your work area. They help absorbing excess moisture and making the blocking process easier.
  • Blocking Pins or Wires: These are used to secure your knitting in place while it dries without leaving marks on your fabric. Pins are handy for pinning knitted items to blocking mats or towels, while blocking wires, such as sock blockers, can be used to maintain straight, even edges and smooth curves, for example on socks.
  • Basin, Sink, or Spray Bottle: You’ll need water to dampen your knitted piece before stretching it into shape. A spray bottle, sink, or basin of water works well for this purpose.
  • Wool Wash or Mild Detergent: Use a gentle detergent or wool wash to remove any dirt or oils from the fibers during soaking.
  • Clean Towel: Use this to gently squeeze out excess water from your knitting before blocking.
  • Space for Drying: You’ll need a flat, dry area where you can leave your knitting piece to dry completely in its stretched state.

With these tools at your disposal, you’ll be well-equipped to block your knitting like a pro!

Step-by-Step Instructions

Blocking knitting is a straightforward process that requires minimal equipment and expertise. Here’s a detailed step-by-step guide to help you get started.

Step 1: Lay Out Blocking Mats or Towels: Prepare a clean, flat surface with blocking mats or towels to shape your knitting. This provides stability and protection for your work area.

Step 2: Prepare Your Knitted Piece: Ensure your knitted item is clean and ready for blocking.

Step 3: Dampen Your Knitting: Fill a basin or sink with lukewarm water and a bit of gentle wool wash or mild detergent. I like using Eucalan as it doesn’t need to be rinsed, causing less stress on fibers. It has a neutral scent and leaves the work nice and soft. Then submerge your knitting and let it soak for about 15 minutes. Alternatively, you can do this by spraying it with a water bottle.

Step 4: Gently Remove Excess Water: After soaking, carefully lift your knitting out of the water and gently squeeze out the excess water from your knitting. Avoid wringing or twisting to prevent damage. I usually first squeeze out the excess water by using my hands and then I wrap the knitted item into a towel and squeeze out the rest of the water into the towel.

Step 5: Shape Your Knitting: Lay your damp knitting flat on the blocking mats or towels and gently shape it to its desired dimensions. You can do this by hand, pulling on the fabric to smooth out any wrinkles or uneven areas and ensure an even fit.

Step 6: Secure with Pins or Wires: Use blocking pins or wires to secure your knitting in place on blocking mats or towels, focusing on the edges and any areas that need shaping. This helps maintain their shape as they dry. If you’re using sock blockers, you can simply hang them of the end or place them flat on a blocking mat or towel.

Step 7: Let it Dry Completely: Once you’ve shaped your knitting, leave it to dry completely in its stretched state. This can take anywhere from a few hours to overnight, depending on the yarn and the humidity levels in your environment.

Step 8: Reshape if Necessary: If the knitted piece loses its shape during drying, you can reshape it by hand before it fully dries.

Step 9: Remove Pins or Wires: Once dry, carefully remove the pins or wires from your knitting. Your blocked piece should now be ready to wear or display!

Blocking Mistakes To Avoid

When blocking knitting, it’s essential to avoid the following mistakes.

Skipping the Soaking Step: Properly soaking your knitting before blocking is crucial for relaxing the fibers and achieving even shaping. Skipping this step can result in uneven blocking and less effective results.

Using Incorrect Water Temperature: Using water that is too hot can damage delicate fibers, while water that is too cold may not effectively relax the fibers for shaping. Stick to lukewarm water for best results.

Overstretching: Pulling and stretching your knitting too forcefully during blocking can distort the fabric and alter the intended dimensions of your project. Be gentle and avoid excessive tension when shaping.

Using Inappropriate Blocking Materials: Using materials that are not suitable for blocking, such as cardboard or newspaper, can lead to uneven drying and potentially damage your knitting. Invest in proper blocking mats or towels to provide a flat, clean surface for blocking.

Not Allowing Sufficient Drying Time: Rushing the drying process can result in incomplete blocking and may cause mildew or mold to develop in damp areas. Allow your knitting to air dry completely before removing pins or wires.

Neglecting to Check Measurements: Failing to double-check your knitting’s dimensions before and after blocking can result in unexpected changes in size or shape. Use a tape measure or ruler to ensure accuracy throughout the blocking process.

Using Too Much Steam: When steam blocking, be cautious not to hold the steamer too close to the fabric or apply too much steam, as this can cause damage or distortion to the fibers.

By avoiding these common mistakes, you can ensure that your blocking process is effective and that your knitting projects turn out beautifully.
