How To Block A Cardigan Sweater? – Judith Clark Costume

Blocking a cardigan sweater is an important step to settle the knit stitches into place, stretch and reveal lace patterns, and allow the yarn to bloom and the collection of knit stitches to become a unified piece of fabric3. Here are some steps to block a cardigan sweater:

Fill your sink or basin with lukewarm water and wool wash if desired3.
Gently wet your sweater3.
Take your sweater out of the water and gently squeeze out the excess water. Do not wring or twist your sweater3.
Lay your sweater flat on a clean towel and roll it up to remove more water3.
Unroll the towel and lay your sweater flat on a blocking mat or another pinneable surface6.
Gently adjust your garment until the piece is the desired shape and size6.
If your garment is a cardigan, overlap the bands and use pins to place4.
Leave your sweater to dry completely before unpinning and wearing it3.

Preparation

Before you begin blocking your cardigan sweater, there are a few things you need to have on hand. Gather the necessary materials, including a clean basin or sink, mild detergent, blocking pins, a blocking mat, and a tape measure. These items will be essential in the blocking process.

Once you have your materials ready, it’s time to choose the blocking method that best suits your needs and the fiber content of your cardigan. Wet blocking, steam blocking, and spray blocking are the three most common methods. Each method has its advantages, so consider the fiber content and desired outcome before making your decision.

Washing

Before you start the blocking process, make sure to check the washing instructions for your cardigan. Different fibers require different care methods, and it’s important to follow the manufacturer’s recommendations to avoid damaging the fabric.

If the washing instructions indicate that machine washing is safe, you can proceed with washing the cardigan. Use a gentle cycle and mild detergent to prevent any potential damage. If handwashing is recommended, fill a basin or sink with lukewarm water and a small amount of detergent. Gently agitate the cardigan in the water, being careful not to stretch or wring it.

After washing, rinse the cardigan thoroughly to remove any soap residue. Gently squeeze out excess water, but avoid twisting or wringing the fabric. Instead, lay the cardigan flat on a clean, absorbent towel and roll it up to remove more moisture.

Dry the Cardigan

After washing, it’s time to dry your cardigan before moving on to the blocking process. Lay the damp cardigan flat on a clean, dry towel or blocking mat. Gently reshape the cardigan to its original dimensions, smoothing out any wrinkles or puckering. Allow the cardigan to air dry completely in a well-ventilated area, away from direct sunlight or heat sources.

Blocking Method 1: Wet Blocking

If you’ve chosen the wet blocking method, here’s what you need to do. Start by soaking the cardigan in lukewarm water for about 15 to 30 minutes. This will help the fibers relax and become more pliable.

While the cardigan is soaking, prepare your blocking mat by laying it flat on a clean, dry surface. Retrieve your blocking pins and have them readily available.

Once the soaking time is complete, remove the cardigan from the water and gently squeeze out any excess moisture. Place the cardigan on the blocking mat, and using your blocking pins, secure the edges of the cardigan to the desired measurements. Take care to maintain the original shape of the cardigan as you pin it.

After pinning, gently shape the cardigan by tugging and adjusting it. Pay attention to any specific areas that may require more shaping, such as the neckline or sleeves. This shaping will help the cardigan maintain its proper fit and aesthetic.

Blocking Method 2: Steam Blocking

For steam blocking, the process is a little different. Instead of soaking the cardigan, you’ll use steam to relax the fibers and allow them to be shaped.

Start by hanging the cardigan on a hanger or draping it over a clothesline. Using a handheld steamer or iron with steam function, carefully steam the cardigan, moving the steamer in a gentle, sweeping motion. Be cautious not to touch the garment directly with the iron or steamer, as it may cause damage.

Once the cardigan is evenly steamed, place it on the blocking mat. Using your blocking pins, secure the edges of the cardigan to the desired measurements, paying attention to the original shape of the garment. Now, gently shape the cardigan by tugging and adjusting it to ensure it retains its proper fit and form.

Blocking Method 3: Spray Blocking

Spray blocking offers a convenient alternative to wet or steam blocking. To spray block, prepare a blocking spray solution by mixing water and a blocking agent, such as a wool wash or fabric softener. Transfer the solution into a spray bottle for easy application.

Lay the cardigan flat on a clean, dry surface, such as a blocking mat. Spray the cardigan evenly with the blocking solution, making sure to saturate the fibers. Be mindful not to oversaturate, as excessive moisture can lead to longer drying times.

Once the cardigan is sprayed, prepare your blocking mat and have your blocking pins within reach. Pin the edges of the cardigan to the desired measurements, being careful to maintain its original shape. As with other blocking methods, gently shape the cardigan by tugging and adjusting it to ensure proper fit and form.

Blocking Tips

Blocking can be a delicate process, and attention to detail is crucial. Here are some tips to help you achieve the best results:

Use Blocking Pins

Invest in a set of quality blocking pins specifically designed for blocking knitwear. These pins are sharp enough to hold the fibers securely in place but won’t damage the fabric. This will ensure your cardigan stays in place while drying and retains its shape.

Be Mindful of Cardigan’s Fiber Content

Different fibers react differently to blocking methods. Natural fibers like wool or cashmere have more resilience, while synthetic fibers may require more gentle treatment. Always check the fiber content of your cardigan and adjust your blocking method accordingly to avoid any potential damage.

Test Blocking on a Small Area

If you’re unsure about the blocking method or concerned about how the fabric may react, it’s a good idea to test the process on a small, inconspicuous area of your cardigan. This will help you assess the outcome without risking the entire garment.

Allow Sufficient Drying Time

It’s important to let your cardigan fully dry before unpinning it. Depending on the fiber content and the level of moisture, this can take several hours or even a day. Avoid rushing the drying process, as removing the pins too early can cause the cardigan to lose its shape.

Finishing the Process

Once your cardigan is completely dry, it’s time to unpin and inspect the blocked garment. Carefully remove the blocking pins, being mindful not to snag the fabric. As you take off the pins, observe how the cardigan has transformed in shape and structure.

Inspect the blocked cardigan, focusing on areas that were problematic before blocking. Check for evenness in stitch tension, as blocking can help smooth out any unevenness. If you notice any areas that still require reshaping, gently tug and adjust the fabric to achieve the desired outcome.

Common Mistakes to Avoid

Blocking can be a meticulous process, so here are some common mistakes to avoid:

Not Checking Washing Instructions

Failure to check the washing instructions can lead to irreversible damage to your cardigan. Always review the care label and follow the manufacturer’s recommendations for washing and blocking.

Using the Wrong Blocking Method

Different fibers and knitting patterns may require different blocking methods. Be sure to choose the appropriate blocking technique that suits your cardigan’s fiber content and desired outcome.

Rushing the Drying Process

Patience is key when blocking a cardigan. Rushing the drying process can lead to a misshapen or damaged garment. Allow sufficient drying time to ensure your cardigan retains its shape and integrity.

Benefits of Blocking

Blocking your cardigan offers a range of benefits that enhance the overall appearance and wearability of the garment. Here are some advantages:

Enhances Shape and Fit

Blocking helps shape your cardigan, allowing it to better conform to your body. This improves the fit and ensures a flattering silhouette.

Evens Out Stitch Tension

If you’ve encountered varying stitch tension in your cardigan, blocking can help even it out. The gentle stretching and reshaping of the fibers create a more uniform fabric appearance.

Allows the Fiber to Relax

Blocking allows the fibers of the cardigan to relax and bloom, enhancing their natural drape and softness. This results in a more luxurious and comfortable wearing experience.

Adds a Professional Finish

Blocked cardigans have a polished, professional look that elevates their aesthetic appeal. Whether you’re wearing your cardigan casually or for a formal event, blocking enhances its visual appeal.
