How To Spray Block

I picked up my blocking board last week, and I thought a wee tutorial might be in order. Click any photo for more information, or check out the full photo tutorial on Flickr (there are about twice as many photos there*).

Blocking is the process of setting your fiber pieces with some form of water. You can spray block (demonstrated here), wet block (using a similar technique but starting by submerging your pieces in water until they're saturated), or steam block (using a steamer or a steam iron after you pin the dry pieces). Blocking almost always works magic on natural fibers and blends. Results are less predictable with synthetics. There are several benefits to blocking:

• Blocking sets the shape of your pieces (e.g., you can even out edges or help correct unwanted curling).
• Blocking relaxes and evens out your stitches.
• Blocking can dramatically improve the drape of your fabric.
• You can slightly adjust the finished size of your fabric by blocking it. (You can block it to be bigger, but not to be smaller.)

Gather the following before you begin:

• Some completed granny squares
  
• A flat surface (like a blocking board [used here], bed, carpet, or stack of towels)
• Rustproof pins
• Spray bottle filled with tepid water

1. Note the finished dimensions of the squares. In this example I'm blocking both standard 7-round granny squares (pictured on the right) and several different-size squares for my Babette Blanket (on the left). The standard grannies need to be 7.5“ square, and the largest-to-smallest Babette squares need to be 15”, 5“, and 2.5” square, respectively.

2. Leaving breathing room between them, lay your squares out on a flat surface. In this example I'm using a blocking board**. You could also use a mattress (remove blankets first), a clean carpet, or a stack of towels. The bonus of using a blocking board is the super handy grid printed on the fabric lining (also, the lining wicks moisture to speed drying). You could make yourself a blocking board using foam board and fabric.

3. Grab some pins (but not really; you'd stick yourself). Pin the first corner of the square; any corner will do. If you're using a grid, make sure to position the square on the grid so that it's easy to measure in both directions so you can determine where to pin the other corners.

4. Pin the corner diagonally opposed to the first corner. Continue to pin the remaining two corners. Measure to make sure the pins are equidistant from each other along the edges. In this example, each edge is now 7.5“ across. I had to stretch the edges slightly to achieve this.

5. Notice in the previous photo that pinning the corners caused the edges to curve. Correct this by pinning the center of each edge to the proper dimension. Continue pinning until the edges are flat and square.

6. Spray the pieces evenly and thoroughly with tepid water. (This is why you should use rustproof pins.)

7. Leave the pieces pinned until they're completely dry. Depending on your climate and the time of day, you might have to leave them overnight. Here are the Babette squares just after spraying:


8. Once dry, remove the pins and enjoy your work. (Photos of dried squares to come tomorrow, when these squares are dry.)

* There are 19 photos in the Flickr set. I took 173 during the shoot.
** I got my board at Three Bags Full in Vancouver, BC. Lots of local yarn stores carry them, as do some online stores.
