For a wool wash, I use Soak because it is a no rinse formula which makes it hassle free and it smells great among many other benefits. I fill my sink up with luke-warm water and add a bit of Soak. I know
this is scary after you spent hours of work on your project... but put it in the water (it will be even more beautiful when it comes out, trust
You can use foam mats for blocking or I like to use a sewing mat. The mat has measurements on it that make it nice and easy to get everything even. (My cats like to use the foam mats as scratching mats when I'm blocking, so I switched early on) Lay your shawl in the middle of your workspace. You can probably see how the water has helped make the lace really stretchy and sometimes its pretty amazing just how big your project actually is. You can decide to block your shawl lightly if you are just wanting to bring out the lace pattern or if you are looking to make the project much larger, you can block it with more force. Remember that your shawl is stronger as a whole than the yarn is by itself. Don't be afraid to block or stretch your fabric. I find that blocking wires are helpful for making straight lines and bringing out points or scallops effortlessly. Because of the shape of this shawl, I used blocking wires for the top of the shawl and pinned the rest. If you were making a triangular shaped shawl, you could use the wires along the top and then through the scalloped edges of the sides. The wires reduce the number of pins you need and if your pins aren't rustproof then you just have to pin the wire down itself and not worry about the pins in your work. To use blocking wires, simply weave one end through the stitches you are wanting accentuated. For this shawl, I thread my wires through the picot points at the top.
