Hi, from one girl to another, we turners call sand paper, grits, and
you start with the lower numbers, and work your way up through to the
higher number grits. The numbers tell you how many particles there are
per square centimetre. (I think that's right). So moving up to a larger
number of particles means you remove more of the scratches you made with the
last piece of grit, until the scratches are so many and so fine that is
feels just like a babies bum. Hope this help make sense of it. Just
lately had to do a lot of sanding down and this time used a random orbital
sander, of what bliss, my arms and wrists didn't need to spend the next
two days recovering.
