How to Spray Block Your Crocheted and Knitted Projects

There's a lovely sense of accomplishment in finishing that last stitch in a handmade piece, whether it's a delicate lace shawl or a cosy cardigan. However, before you declare it done, there's one final step that can make all the difference to how your item looks and drapes: blocking. In this article, we explore spray blocking, which is a gentle, fuss-free technique that enhances the drape, shape, and stitch definition of your finished project without soaking the whole thing.

What Is Spray Blocking and Why Use It?

Spray blocking is a gentle finishing technique where you lightly mist your project with water and shape it as it dries. It’s especially useful for delicate or lightweight yarns that don’t respond well to more aggressive methods like soaking or steaming.

So, when should you reach for spray blocking?

• When working with delicate fibres like mohair, alpaca, art yarns or silk blends
• If you want to maintain the natural texture and springiness of your stitches and/or yarn
• When your piece just needs a bit of reshaping or a soft finish

Spray blocking is ideal when you want to finesse your work without over-handling it—perfect for those final touches that make a project look polished but still feel like you made it.

When to Choose Spray Blocking Over Other Methods

Not all fibres respond well to wet or steam blocking. In fact, those methods can sometimes stretch or flatten your work more than you'd like, especially with delicate yarns. Spray blocking offers a gentle, controlled alternative that’s perfect when precision matters.

Consider spray blocking when:

• You’re working with fine, airy yarns like ITO Sensai or Malabrigo Mohair
• Your yarn is prone to colour bleeding
• Your project just needs a bit of reshaping or a light refresh
• You've used lacework or intricate stitch patterns that need careful setting

Spray blocking lets you fine-tune the finish without overpowering the fabric, helping your stitches stay crisp, your textures stay lively, and your project stay true to your original vision.

Step-by-Step Guide to Spray Blocking

Spray blocking is straightforward and beginner-friendly. With a few simple tools and a bit of patience, you can shape your piece and let those stitches shine.

What You'll Need:

• A spray bottle with a fine mist setting.
• A blocking mat, thick towel, or foam surface.
• Rust Resistant T-Pins or KnitPro Mindful Knit Blockers.
• Optional: a ruler or measuring tape, and no-rinse wool wash.

Let's break it down step by step.

1. Preparing Your Project

Before you begin spraying, get your workspace ready:

• Lay your project flat on a clean blocking surface, such as a blocking mat or thick towel.
• Smooth out wrinkles with your hands or the help of ITO Crochet Hooks
• Avoid tugging or overstretching—just guide it into a natural shape

This preparation ensures even blocking and prevents distortion.

2. Shaping and Pinning

Now for the creative part—shaping!

• Gently stretch or shift the fabric to the desired dimensions.
• Use pins or blockers to secure the edges and corners. Some Shawls may benefit from the use of blocking wires or a length of threaded scrap yarn to help secure the intended shape.
• Check for symmetry, especially on lace or decorative details.

Tip: For curves or scallops, use extra pins to define the shape precisely.

3. Applying Water Evenly

Moisture relaxes the fibres and makes shaping easier.

• Fill your spray bottle with lukewarm water.
• Add a drop of wool wash for extra softness if desired.
• Mist the project evenly from a distance of 20–30 cm.

You want the fabric damp but not dripping. Give it time to absorb the water before moving on.

4. Allowing It to Dry

Proper drying is what sets the shape and locks it in.

• Leave the project to air dry fully—this could take several hours or overnight.
• Place it in a well-ventilated area, away from direct sunlight or heat.
• A fan can help speed things along if needed.

Don't unpin until it's completely dry, or you risk losing your carefully shaped finish.

Troubleshooting Common Spray Blocking Issues

Even with gentle techniques like spray blocking, a few hiccups may arise. Luckily, they're easy to fix and prevent once you know what to look out for.

Here are some common problems and how to solve them:

Uneven Shaping

What’s happening: Your piece dries looking lopsided or asymmetrical.
How to fix it: Lightly re-mist the fabric, adjust or re-pin it, and let it dry completely.
Pro tip: Use a ruler, blocking wires, or a template to keep things even, especially for lacework.

Over-Saturation

What’s happening: The fabric ends up too wet and starts to sag.
How to fix it: Gently blot with a clean towel, reshape, and leave to dry.
Pro tip: Mist in light, even layers—less is more.

Stubborn Wrinkles or Curling Edges

What’s happening: Edges won’t lie flat or parts of the fabric keep curling.
How to fix it: Re-mist the area and use extra pins to hold it in place.
Pro tip: Gently press with your fingers or palm as it dries to help smooth things out.

Colour Bleeding

What’s happening: Dye starts to run, often with hand-dyed or richly pigmented yarns.
How to fix it: Always test a swatch first. If bleeding occurs, blot gently—don’t rub—and let the piece dry undisturbed.
Pro tip: Use only cool water to reduce the risk of dye release.

Shape Doesn't Hold After Unpinning

What’s happening: The project shifts or loses its shape once dry and unpinned.
How to fix it: Try re-blocking with firmer pinning or consider adding a stabilizing border.
Pro tip: Some fibres may benefit from a second light blocking after the first wear to help set the shape more permanently.

Final Tips for Successful Spray Blocking

With the right approach, spray blocking can bring out the best in your handmade pieces. It's a low-stress, high-impact technique that rewards patience and attention to detail.

To get the best results:

• Always test blocking on a swatch first
• Invest in proper tools like blocking pins or mats
• Block in a peaceful space—pets, kids, and breezes can all shift your setup!

Let Your Handmade Masterpiece Shine

Spray blocking is one of those magical finishing touches that transforms a good project into a great one. Whether you're smoothing out lace, refining a scarf's edge, or setting a delicate fibre, this technique helps your work look its very best—without stress or over-handling. So, next time you cast off a project, don't stop there. Give it a light spray, shape it with care, and step back to admire your work in its full glory.
