Blocking is a simple but vital step which will greatly improve the look of even the most beginner knitting. If you have made the effort to hand-knit something, it deserves to be blocked.
Blocking is the process of wetting or steaming your final pieces of knitting to set the finished size and even out the stitches.
You could use any flat surface to block your garments (I'm partial to the Knitter’s Block), just be sure that your knitted piece lies flat and fully dries so that its shape sets. Don't forget to check that moisture doesn't soak through and damage anything underneath it. (This has happened to me, which is why I developed the Knitter's Block — the blocks are backed with waterproof EVA so you can safely block on a bed, table or floor.)
Always block your finished pieces before seaming. By flattening and setting the shape of your pieces, you will be able to more easily line up your stitches to seam them together.
The fiber content of the yarn and the stitch pattern of your knitting will often determine how you block your finished pieces. Below you’ll find instructions on wet blocking, which is my preferred method.
Soak your knitted item in gentle wash per the yarn label instructions.
While your item is soaking, set up the surface that you will be using for blocking. If you’re using the Knitter’s Block, configure the tiles to accommodate your knitted item.
Drain the water, then gently squeeze (don’t wring) your knitting and roll it in a towel to extract as much moisture as possible. We recommend our Super-Absorbent Towel for best results.
Lay your damp knitting right-side up on the your blocking surface and gently nudge the piece to your finished measurements.
If you’re using the Knitter’s Block, place the Check Your Gauge Cloth onto the assembled tiles so it will be under your knitting. Each check measures approximately 1" square. Lay your damp knitting RS up onto the checked cloth and use the checks as a guide to get your correct finished measurements.
Pin the knitted item around the edges, placing the pins at an angle, with the top of the pin pointing away from the garment. Place the first pin in the top center, moving to the bottom center as you pin the piece to the correct length. Next, pin your work to the correct width (if blocking a sweater, start with the bust width). Fill in around the edges, always referring to your finished measurements.
Allow to air dry.
Arrange your damp knitting on your blocking surface and gently nudge and smooth the piece to your finished measurements.
If you’re using the Knitter’s Block, the tiles will gently grip your knitting so that the sweater stays in place. Place the gingham Check Your Gauge Cloth over the knitted item to check sizing if necessary.
To help hold rolling edges down either use a few T-pins or dampen a cloth and use its weight to hold down your knitting.
Allow to air dry.
For light blocking, you can now lift the cloth and allow the knitting to dry.
For medium/heavy blocking, leave the cloth in place until it has dried. If your knitting is still damp, allow it to dry before removing.
Regardless of whether you block with or without steam, make sure your pieces are dry before moving them.
After you have sewn your garment together you may wish to steam the seams, especially if they are bulky or stiff. For shoulder and armhole seams, use a terry cloth hand towel folded and then rolled to the size and shape of your upper arm. Turn the garment inside out and fit the rolled towel into the shoulder and armhole openings. Steam the seams gently by using the wet pressing cloth and steam iron, and just barely touching the pressing cloth with the iron. Let the steam do the work.
