Blocking Knits - It's Magic!

Blocking is really wonderful for knit garments. It evens out stitches and softens the knit; the yarn relaxes and lace opens to show its full beauty. In other words the knit transforms.
When to Block? All animal fibers should be blocked. Plant fibers (cotton, linen, bamboo, rayon) may also be blocked although they respond less dramatically than the animal fibers. Synthetic fibers (e.g.acrylic, nylon) are not blocked unless blended with a natural fiber.

How to Block a Knit
  1. Time and patience:  A sweater or shawl will take several hours to wash and pin out. Sometimes you may need to redo parts or all to insure everything is well aligned and matched.
  2. Prepare garment:  It is best to block a garment before seaming. This makes the washing and seaming easier. Work in ends if they are in the middle of a piece. If ends are on the edges leave these to work in after the garment is seamed. If this is a circular knit the garment is finished completely and then washed and blocked.
Mats like this with 1inch square grid are great for laying out sweater parts. Mat and wires

3. Assemble equipment:
·        Blocking board or surface: This will stay in place until the garment dries so make sure it is not in the way and children or pets cannot walk on it or pick up any pins for their safety. Make sure the surface can hold all the pieces or garment. It is really hard to block over an edge and will make a mark in the knitting.
·        Sink or tub for washing and access to hot water.
·         Shampoo or a gentle soap. Do not use Woolite or dishwashing liquid for wool.  Both of these are too harsh and can damage the wool fibers. White vinegar may also be needed.
·        Pins and maybe blocking wires – see below for more information on these.
·        Two Measuring tapes. Sometimes a yard stick is also handy.
·        Steamer or steam iron.
4. Soak in hand hot water for at least 20 minutes.  Use a small amount of shampoo or a gentle soap.  No need to agitate. Also soak to rinse. I usually rinse three times using white vinegar for protein fibers only in the second rinse to neutralize the soap. Amount of vinegar depends on the amount water. I use about 1 tbs/gallon – guessed, not measured. Some knitters believe leaving a little bit of soap in without complete rinsing may discourage bugs.
5. Remove excess water: Squeeze out the water. Do not twist or wring. If there is a lot of water, roll up the pieces or garment in a towel. Then press firmly on the towel. 
6. Lay out each piece on a blocking board. A clean carpet or bed may work for larger items. Smooth out the garment to its full size without stretching.
7. Align each piece with a straight edge either on the blocking board or use a measuring tape and pin for a straight line you can work from. Do this for the long edges. Shorter edges you can usually tell by looking.  I don’t do this with shaped sleeves – I check just by looking and measuring.
8. Measure the sides and top and bottom to make sure they are all even (unless they are not supposed to be). Make sure both fronts and sleeves are the same measurements-again if they are supposed to be. Check these measurements against your gauge and the planned or pattern finished sizes.
9. Pinning and/or Inserting Wires: If the garment is a bit small on an edge or overall you can stretch it some (there are limits to this). If stretched, it will need pinning to the desired size. Sometimes you only need to pin the corners, sometimes you need to pin every inch along every edge (or use blocking wires). You will know if you need to pin if the edge retracts back when you let go of it. 

I love these blocks (from Knit Picks) for long scarves. 
T pins help save your fingers.

I usually pin scallops, picots and points. Wires are great for lace – just weave them along the edge. Then pin the wires as needed to keep the edges straight.  In dry climates the lace may need to be dampened several times as it may dry before it is completely pinned. A spray bottle with water works well for this. Check that the pattern stitches are aligned and even.  If not re-pin until they are.
The blocks and wires are perfect for shaped shawls as you can put a a block where needed

10. Steam to set. Washing may be enough but I usually steam as a final touch. Always steam if the garment is lace or has been stretched. You can use a steamer or a steam iron. A dry iron and damp cloth can also be used but never press the knit. Pressing will flatten the knitting and ruin stitch definition.
11. Let dry. Remove the pins and wires when the knit is almost dry to prevent pin marks. Leave the pieces or garment in place.  Only pick it up when it is completely dry. If you are working with a finished garment you will need to turn it over as soon as one side almost dry. It may need turning several times.
Enjoy. Your knit has been transformed.
