What is blocking? When you want your work to sit flat and straight and don't want your corners curling you block it. Lay it on a flat surface like a cushion or bed and use pins to straighten your edges and hold down those corners that keep curling up. Once pinned how you like it get a spray bottle and spray with a good mist of water and leave overnight. In the morning unpin and voila your work is neat and tidy and looks stunning.
I used 100% pure merino baby wool from spotlight, the blanket took 1/2 a 50g ball of each colour so I've enough left to do a 2nd blanket of the same size.
Here are some final picks of my finished project, now I just need a friend with a baby to gift it to.
