How to Block a Silk Shawl: Complete Step-by-Step Tutorial

Transform Your Silk Shawl with Proper Blocking

Blocking is the secret technique that transforms a freshly knitted or crocheted silk shawl from good to absolutely stunning. This essential finishing step opens up lace patterns, evens out stitches, and gives your handmade silk shawl the professional drape and shape it deserves.

Whether you've just completed your first silk lace shawl or you're a seasoned knitter looking to perfect your blocking technique, this comprehensive guide will walk you through every step of the process.

Why Block Your Silk Shawl?

Blocking isn't optional—it's essential for silk shawls, especially lace patterns. Here's why:

• Opens Up Lace Patterns – Reveals the full beauty of intricate stitch work
• Evens Out Stitches – Smooths any tension irregularities
• Sets the Shape – Creates clean edges and symmetrical points
• Enhances Drape – Allows silk's natural fluidity to shine
• Professional Finish – Gives your handmade piece a polished, gallery-worthy appearance
• Increases Size – Silk can grow significantly when blocked, maximizing your yardage

What You'll Need

Essential Blocking Supplies

• Blocking Mats – Foam interlocking tiles or blocking boards (at least 3-4 feet square for most shawls)
• Rust-Proof Pins – T-pins or blocking pins (you'll need 100-200 depending on shawl size)
• Measuring Tape – To ensure symmetry and desired dimensions
• Clean Towels – For absorbing excess water
• Basin or Sink – Large enough to submerge your shawl
• Gentle Detergent – pH-neutral wool wash or silk-specific cleanser
• Spray Bottle – Optional, for misting if needed
• Blocking Wires – Optional but helpful for long straight edges

Optional but Helpful

• Pattern schematic or finished measurements
• Camera to document the process
• Fan to speed drying (on low, indirect)
• Ruler or straight edge for alignment

Step-by-Step Blocking Tutorial

Step 1: Prepare Your Shawl

Weave in All Ends

• Secure all yarn tails before blocking
• Trim ends close to the fabric
• Check for any loose stitches or repairs needed

Review Your Pattern

• Check the pattern for recommended finished dimensions
• Note any special blocking instructions
• Decide on your desired final size

Step 2: Soak Your Shawl

Fill Your Basin

• Use cool to lukewarm water (never hot)
• Add a small amount of gentle wool wash or silk detergent
• Swirl to distribute soap evenly

Submerge the Shawl

• Gently place your shawl in the water
• Press down gently to ensure it's fully saturated
• Let it soak for 10-15 minutes
• Do not agitate, rub, or wring

Rinse Thoroughly

• Drain soapy water and refill with clean cool water
• Gently press to rinse out all soap
• Repeat until water runs clear
• Optional: Add 1 tablespoon white vinegar to final rinse for extra luster

Step 3: Remove Excess Water

Gentle Squeezing

• Lift shawl carefully, supporting its weight
• Gently squeeze (never wring or twist) to remove excess water
• Work from center outward

Towel Rolling

• Lay a clean, dry towel on a flat surface
• Place shawl on towel and roll up like a burrito
• Press firmly to absorb moisture
• Unroll and transfer to a fresh dry towel if very wet
• Shawl should be damp, not dripping

Step 4: Set Up Your Blocking Surface

Prepare Blocking Mats

• Arrange foam mats on a flat surface where they can remain undisturbed for 24-48 hours
• Ensure surface is level
• Place in a location away from direct sunlight and heat
• Make sure you have adequate space for your shawl's full dimensions

Plan Your Layout

• For triangular shawls: plan for center point at top, two bottom points
• For rectangular shawls: ensure you have space for full length and width
• For circular shawls: plan for even radial pinning

Step 5: Pin Your Shawl

Start with the Center

• For triangular shawls, pin the center top point first
• For rectangular shawls, pin one corner
• Ensure this anchor point is secure

Work Outward Systematically

• Gently stretch the shawl to desired dimensions
• Pin major points first (corners, pattern repeats)
• Use measuring tape to ensure symmetry
• For lace patterns, pin through each point or scallop
• Space pins 1-2 inches apart along edges
• Stretch gently but firmly—silk can handle more tension than you think

Special Techniques

• Blocking Wires: Thread through edge stitches for perfectly straight edges, then pin the wire at intervals
• Lace Points: Pin each point individually to open up the pattern fully
• Scalloped Edges: Pin the peak of each scallop and the valley between
• Symmetry Check: Measure from center to each edge point to ensure evenness

Step 6: Final Adjustments

Check Your Work

• Step back and view the overall shape
• Verify measurements match your desired dimensions
• Ensure lace patterns are fully opened
• Check that edges are smooth and even
• Adjust pins as needed

Mist if Needed

• If any areas have dried during pinning, lightly mist with water
• Ensure entire shawl is evenly damp
• Don't oversaturate

Step 7: Drying

Patience is Key

• Allow shawl to dry completely—typically 24-48 hours
• Do not disturb or move during drying
• Ensure good air circulation in the room
• Optional: Use a fan on low setting (not directly on shawl)
• Never use heat to speed drying

Test for Dryness

• Touch the thickest parts (where yarn overlaps)
• Check underneath the shawl
• Ensure completely dry before unpinning

Step 8: Unpinning

Remove Pins Carefully

• Once completely dry, remove pins systematically
• Work from edges toward center
• Support the shawl as you unpin
• Check for any pins you might have missed

Final Inspection

• Gently lift and admire your beautifully blocked shawl
• Check for any areas that need touch-up blocking
• Your shawl should maintain its blocked shape

Blocking Different Shawl Shapes

Triangular Shawls

• Pin center top point first
• Measure and pin two bottom points equidistant from center
• Pin along top edge, ensuring straight line
• Pin diagonal edges, maintaining symmetry
• Pin bottom edge, opening up any lace border

Crescent Shawls

• Pin center of curved edge first
• Pin two end points
• Work along curve, pinning each lace repeat
• Ensure even curve throughout

Rectangular Shawls/Stoles

• Pin all four corners first
• Measure to ensure rectangle is true
• Pin along all edges at regular intervals
• Pay special attention to keeping edges straight

Circular Shawls

• Pin center point if applicable
• Divide circle into quarters and pin those points
• Continue dividing and pinning radially
• Ensure even circle shape

Pro Tips for Perfect Blocking

Maximize Your Results

• Block Generously – Silk can handle aggressive blocking; don't be timid
• Use Plenty of Pins – More pins = better definition
• Measure Twice – Check symmetry frequently during pinning
• Document Measurements – Record final dimensions for future reference
• Block Every Time – Re-block after each washing to maintain shape

Common Mistakes to Avoid

• Unpinning before completely dry (causes shawl to shrink back)
• Using too few pins (results in wavy edges)
• Blocking in direct sunlight (can fade colors)
• Rushing the drying process with heat (damages silk fibers)
• Not checking symmetry (results in lopsided shawl)
• Wringing or twisting when wet (distorts stitches)

Troubleshooting Blocking Issues

Shawl Won't Stay Blocked

Problem: Shawl returns to pre-blocked size after unpinning

Solution: Ensure shawl was completely dry before unpinning. Silk holds its blocked shape well when fully dry.

Uneven Edges

Problem: Edges are wavy or irregular

Solution: Use more pins spaced closer together. Consider blocking wires for perfectly straight edges.

Lace Pattern Not Opening

Problem: Lace looks closed or tight

Solution: Block more aggressively. Pin each individual lace point. Silk can handle significant stretching.

Water Spots

Problem: Spots appear during drying

Solution: Mist entire shawl evenly to blend spots, or re-wet and start blocking process again.

Maintaining Your Blocked Shawl

Between Wearings

• Fold gently and store flat
• Avoid hanging (causes stretching)
• Store in breathable cotton bag
• Keep away from direct sunlight

After Wearing

• Air out before storing
• Spot clean if needed
• Re-block after washing

Long-Term Storage

• Clean before storing
• Fold with acid-free tissue
• Store in cool, dry location
• Refold periodically to prevent permanent creases

Special Considerations for Different Silk Types

Mulberry Silk

• Blocks beautifully with excellent shape retention
• Can handle aggressive blocking
• Maintains luster after blocking

Recycled Sari Silk

• May have more texture variation
• Block gently to preserve character
• Expect some color variation when wet (normal)

Silk Blends

• Follow blocking guidelines for the predominant fiber
• May require less aggressive blocking than 100% silk
• Check pattern recommendations

When to Re-Block

Your silk shawl will need re-blocking:

• After each washing
• If it loses shape from wear or storage
• When you want to resize it
• After making any repairs
• Seasonally if stored for long periods

The Reward of Proper Blocking

Blocking transforms your handknit silk shawl from a collection of stitches into a work of wearable art. The time and care you invest in this final step will be rewarded every time you wear your shawl and receive compliments on its professional finish and beautiful drape.

The first time you block a silk lace shawl and watch the pattern emerge in all its glory is truly magical. Each subsequent blocking becomes easier as you develop your technique and confidence.

Your Blocking Journey

Remember, blocking is a skill that improves with practice. Your first attempt might feel awkward, but by your third or fourth shawl, you'll be pinning with confidence and precision. Don't be afraid to experiment with different techniques to find what works best for you and your projects.

The beauty of silk is that it's forgiving—if you're not happy with your first blocking attempt, you can always re-wet and try again. Take your time, enjoy the process, and celebrate the transformation of your handmade treasure.

Happy blocking, and may your silk shawls always drape beautifully!
