Blocking is the difference between a handmade-looking project and a professional-looking one. It evens out stitches, opens lace, sets shape, and removes curling. You need specific tools to do it right.

Blocking Methods

Wet blocking: Soak in water, pin to shape, air dry. Best for natural fibers (wool, cotton, alpaca). Most effective method. Takes 24-48 hours to dry.

Steam blocking: Hold steam iron above fabric, then pin to shape. Faster than wet blocking. Best for acrylic and synthetic blends. Works in minutes.

Spray blocking: Mist with water, pin to shape. Lighter blocking, good for minor adjustments and blocking between wears.

Essential Components

• Blocking mats: Interlocking foam tiles (like puzzle pieces). Protect surfaces, hold pins, let air circulate underneath.
• T-pins: Rust-resistant pins with T-shaped heads. Easier to insert and remove than straight pins. You need 50-100 for most projects.
• Blocking wires: Stainless steel wires threaded through edges for straight lines. Essential for shawls, blankets, and anything with long edges.
• Blocking spray: Light starch or water-based solution. Optional but helps set shape.

Blocking Tips

• Block gauge swatches first to predict final measurements
• Pin corners and midpoints first, then fill in edges
• Use blocking wires for straight edges, pins for curves
• Dry flat on a surface with airflow (not carpet — it traps moisture)
