Blocking is essential for lace patterns, because the pattern doesn't open up until you block it. The pattern will remain nearly invisible otherwise, so it's really worth it.

In order to block your garment, you need a frame that is the size your garment needs to be. Alternatively, you need a flat surface you can insert needles into. You fasten the garment on the frame/surface. Now is the first time you can really appreciate its beauty. ;) Then lightly wet your garment and leave it to dry. Done!
