Spray Blocking
Spray blocking uses a spray bottle to dampen a finished piece, then pins it to dry. The technique is intermediate in intensity between steam blocking and wet blocking — gentler than wet blocking but more effective than steam.

Method
Pin the piece flat to a blocking mat in the desired shape. Use a fine-mist spray bottle to dampen the entire piece evenly. Let dry completely before unpinning (typically 6–12 hours).
When to use
Mid-range projects: hats, mittens, small accessories. Garments where wet blocking would be excessive but steam blocking insufficient. Re-blocking after a wash to refresh the shape.

Best for
Projects where the gauge needs only minor adjustment. Garments worn frequently that need regular re-blocking. Knitters in apartments without space for full wet blocking.
Limitations
Less dramatic block than full wet blocking. Less suitable for opening lace patterns. Some yarns (alpaca, mohair) need more water for the fibres to fully relax.

Tips
- Use a fine-mist spray bottle for even dampening.
- Spray block for routine touch-ups; wet block for full transformations.
- Pin to the desired shape before spraying — the wet fabric is harder to pin.
In depth
Spray blocking is a useful intermediate option between steam blocking and wet blocking. The technique provides more shape-setting than steam can achieve while requiring less water and shorter drying time than full wet blocking.
