Blocking is an essential but often overlooked step in knitting. Once a project is off the needles, blocking is like waving a magic wand over your knitting to bring it from good to great – yarn blooms to incredible softness, stitches smooth out to a uniform look, and lace stitches transform to a delicate beauty.
Today we’re going to talk about the two main ways to block knitting projects, as well as offer tips for specialized knits.
Recommended for wool and animal fibers in general, wet blocking involves fully wetting your finished pieces.
First, fill a clean sink or basin with water. For water temperature and soaking time, follow the yarn label's recommendations for the yarn used. Generally, we recommend using lukewarm water (hot water may cause felting in wool!). If using, add wool wash to the bath and swish to distribute evenly.
To soak, gently submerge your project, gently squeezing out any air bubbles so that the piece is fully saturated. Never place any animal fiber items under running water as this agitation may felt your fabric.
Allow the piece to rest in the bath for at least 10 minutes and up to 30 minutes. To remove your project, gently lift it out of the water, making sure to support its weight evenly so that the fabric doesn’t stretch and distort under the extra water weight. Gently squeeze (never wring!) to remove excess water.
Next, lay your project flat on a clean, dry towel.
Roll your project up in a single layer or fold into thirds to make the rolling size more manageable. Press gently and evenly on the rolled towel to remove excess moisture before unrolling and laying your garment flat to completely dry.
To block a garment or project to specific dimensions, lay your project on blocking mats or another pinneable surface. Gently adjust your garment until the piece matches the pattern’s finished measurements or schematic dimensions. Use T-pins when necessary to maintain precise dimensions during the drying process.
This method is recommended for delicate lace projects, cottons, and for gently refreshing garments between wears. It allows you to block without the danger of stretching under water weight, as in wet blocking. Spray blocking is also a much faster method if you’re dealing with a thin, single layered piece as with lace shawls or light accessories.
Place your project on the blocking mats and lightly spray your project with either ready-made spray wool wash or a diluted mix of wool wash and water in a regular spray bottle (to dilute regular wool wash, follow the manufacturers instructions on the bottle). Your project should be damp but not soaking wet; gently shape to approximately match the finished schematic/dimensions.
We recommend using lace blocking wires for straight edges and perfect points on shawls, scarves, and blankets. Carefully thread your blocking wires through selvage stitches at regular intervals across the edges and/or through the "points" if your pattern features them as part of the design.
Once you have inserted your blocking wires, place pins along the inside of each wire at periodic, even intervals while stretching your project to the desired dimensions. Inserting pins at a 45 degree angle will keep the wires more stable as the fabric dries, especially if you are blocking under pressure to get a larger size.
When your piece is fully dry, unpin and wear!
