Blocking is a misunderstood and even contentious topic in the world of crochet. It’s a personal preference among crocheters whether or not to block their work. Some people believe that only wool goods can be blocked, and that blocking synthetic crochet blankets is a waste of time and effort.

When I finished my last stripe on the Attic24 crochet blanket, I realized I needed to do something about the untidy appearance. That’s why I did some research on how to block acrylic crochet blankets.

The part of my crochet acrylic blanket that worried me the most had a shaky edge on the short left side. I started with a hook that was two sizes larger than the one I used to make the main blanket, and worked the foundation chain loosely with that larger hook. In addition, I was concerned by what appear to be unequal frills around the long edge.

On Facebook, I became even more concerned. Would the rows have been equal? Was there a difference in the number of stitches on one side versus the other? Eeeeeeek.

What is Blocking in Crochet?

Crochet items can be shaped using water through the process of blocking. Once it’s dry, it’s pinned down on a blocking board to preserve it in the same shape. A good illustration of how blocking might benefit you is if you’d like to reduce the curling or unevenness of your edges.

Is my Attic24 crochet blanket a rectangle?

No matter how many times I checked my stripes to make sure I hadn’t gained or lost stitches (I was working to 183 stitches in each stripe), I was still concerned and took my time counting the stitches in the border on both sides. The short and long sides both matched up. As a result, it’s unlikely to be anything major. Acrylic crochet blanket’s shape is more distorted on the older portion than the end I just finished, so I guess it’s just relaxed more and stretched around as I worked on the earlier area. Toward the end, because the weather was so chilly, I felt like I was nearly cocooned in my work.

Is blocking acrylic crochet blankets even possible?

What was the first question I had to answer in relation to the debates regarding blocking? The more I learned about steam blocking crochet acrylic blankets, the more I was inspired by Lucy of Attic24. You may, however, block acrylic crochet blankets if you pin them in place, spray them with water, and leave them to dry for 24 to 48 hours. Wool crochet blankets and other things made of wool or a wool blend can be blocked using this approach. Because wool is a natural fiber, it shrinks when wet, which is why steam blocking wool blankets work.

Wetting and drying the wool fibers repositions them, but only little. You need steam to block acrylic crochet blankets, not because of the water, but because of the heat.. When heated and then cooled, the acrylic yarn’s synthetic fibers become permanently fixed. With a steam iron, the Attic24 method of blocking acrylic crochet blankets moves it 3 cm above the crocheted fabric that has been placed in place on an ironing board. Keep your distance from the iron, which will melt the acrylic yarn and damage all of your hard work.

How I decided to block my acrylic crochet blankets

After that, my second question was, “How in the world can I block a blanket?” I sat down and stitched a few border squares while contemplating this. That’s when I got going again… The first thing I did was lay the blanket flat on a carpet to check how crooked it was.

Rather than using pins, I’ve smoothed out the blanket and aligned the edges with the carpet pattern. Fortunately, the carpet that came with the house — and which I despise — ended up serving a purpose. Once I was satisfied with the final shape, I spent about an hour pinning down the corners and modifying it until it was as close to flawless as I could get it.

Steam blocking my acrylic crochet blanket was the next step.

  • For this task, I purchased and installed an extension cord, then plugged in a steam iron and filled its water tank.
  • While on my hands and knees moving the iron about and hovering it 3cm (just over an inch) over the blanket, I checked to see if there was enough steam and if the blanket had heated up to a temperature that was comfortable for me. Bum in the air, yelling with glee at something. There’s a good reason why there aren’t any photos.
  • After I finished with the edges, I knelt down on both sides of the blanket and pressed the iron back and forth over the fabric.

It was time to go to sleep once I finished ironing my clothes.

After blocking my acrylic crochet blanket

After unpinning the blanket this morning, I brought it to the hard floor in my office to take a test image…. It’s definitely gotten better. Some ruffles remain around the blanket’s edging, but I plan to add a substantial amount more to smooth them out. In addition, I discovered that the iphone’s camera distorts the blanket’s contour when taken as an image. Even though it appears to be out of shape, the bottom right corner of the blanket is completely aligned with the straight things surrounding it. The ruffles will be solved as I finish the border. A nice Facebook advice was to alternate rows of the border on the right side and the wrong side to keep the border and blanket edge flat. You can try this once I’ve finished the strip of colorful squares that will run along the blanket’s top and bottom.

Using this method to block acrylic crochet blankets seemed to work, as my blanket now folds up more neatly and the edges line up. Though I’ve finished all but the border of the blanket, it still needs a lot of work even though it looks better. I’m hoping to finish the blanket in time for Christmas – it’d be quite the accomplishment to do so in the six weeks leading up to my birthday in November and the day after Christmas!

How to Block Crochet Patterns

Wet Blocking

In terms of simplicity and ease of learning, the wet blocking technique wins hands down. This method is suitable for a wide range of yarns, and it works really well.

  • Washing or submerging your item completely in water is the only option.
  • Towel-dry the sheet. You may have to repeat this step several times to bring the project to a point where it’s nearly dry.
  • To block your work, you can use a blocking board or a towel to lay it flat.
  • Allow the item to air dry completely.

Steam Blocking

All natural yarn items should be blocked using steam. Even if this works with acrylic yarn, there are better ways to do so.

  • A flat surface is ideal for laying out the object.
  • Wrap a moist cloth around your object.
  • Slowly push the iron or steamer against the damp washcloth to generate steam.
  • While you’re working on it, give it some shape.
  • Allow to air-dry.

Spray Blocking

Spray blocking can be used with any type of yarn, however it may not always function as well as the others. In my perspective, submerging or water-blocking the product in water soaks the fibers more thoroughly than spraying, which is why I prefer this method over spraying.

  • Prepare a cloth or blocking board and place the item flat on top.
  • While you’re shaping your hair, use a water bottle to mist it.
  • The blocking board is available for your use if you so desire.
  • Allow to air-dry.
