What Other Methods Can Be Used To Block Acrylic Yarn?

Several other methods can be used to block your acrylic yarn if a hair dryer is not available or you are scared of your yarn being killed.

There are other  4 methods of blocking available for blocking your acrylic yarn. However, this works perfectly based on the type of needlework used for the project. For example, wet blocking works well for a  crochet acrylic yarn finished work, though not as perfect as using a hair dryer, but it does not work well for a knitting project.

1. Wet Blocking

This is one of the blocking methods which is also best for blocking acrylic yarn finish projects. However, it only works for crocheted acrylic yarn but fails to block knitted acrylic yarn perfectly.

This can be done by simply following the steps below;

  • Fill your bathtub or plastic tub halfway with clean water.
  • Fold your finished project vertically and horizontally.
  • Soak the folded finished project in the water for 20 to  25   minutes, ensuring that the project is fully submerged.  
  • Prepare your blocking mat or towel, noting where to pin when you place your finished project using the measurement.
  • Remove your finished project from the water and gently squeeze out the excess water to prevent the project from stretching.
  • Place on a towel and fold the project in the towel.
  • Roll the towel over the project and press gently to allow the water to come out.
  • Place the project on the blocking mat, pinning it down at the edges or where you have placed the pin.
  • Allow it to dry overnight; once a side is dry, turn to the other side to permit even drying.

2. Spray Blocking

It is also easy to practice, as you only need a spray bottle, pin, and blocking mat. However, it might not give your desired shape, but it can be used for your acrylic yarn by people who do not like blocking their finished project but still love to have a shaped project.

This method will not give you a perfect edge but will only adjust the edge for you when using acrylic yarn. It can be used for your acrylic yarn project using the following  steps;

  • Lay your project on a flat surface or a blocking mat.
  • Pin down the edges roundabout.
  • Fill the spray bottle with water.
  • Spray the projects, pressing them with your free hand.
  • Allow it to dry before removing the pins.

3. Steam Blocking

Steam blocking is not a permanent method for blocking acrylic yarn as it does not work perfectly compared to using a hair dryer or wet blocking.

However, there is a need to be careful due to the high possibility of getting your yarn destroyed in the blocking process, as you will be using a steam iron to get that done.

This can be done by following the steps below;

  • Lay your project on the blocking mat and pin it at the edges.
  • Fill the steam iron water tank with water.
  • Plug in your steam iron and hover it across your project by maintaining a 4 to 5-cm distance from your project.
  • Check your acrylic project while steaming for any signs of melting; once you notice that, stop blocking and allow it to cool; it simply means the iron is too hot.
  • Make sure your project conforms to your desired shape by applying heat above the pinned area.
  • Allow it to cool off before removing the pins.

One very important thing to note is not to place a cloth on the acrylic yarn to press, as the yarn is delicate and can get melted easily through direct heat contact.

4. Use The Washing Machine And Dryer

This method is called the automatic method, as the major thing used is a washing machine and a dryer. Place your finished project in the washing machine before moving it to the dryer (it is best to do that with other clothes).

Remove the damp project from the dryer and place it on a  flat surface, pressing it down with your hand and allowing it to dry completely. You will be surprised by the almost perfect result when your project dries up.
