Pinterest help !

Hello again, just a really quick question, I'm sure someone out-there will know, I've just started a Pinterest page and I want to put a pin it button on my blog, I've copied the link and followed the instructions, but it hasn't worked so far, does anyone know what to do, sorry it's such a boring post,I promise not to do it again. ( No Rabbits dress still isn't finished ! )

update,

thank you  for your help. i have now found the pinterest button,and after only a small amount of stupidness on my part ( serves me right for thinking i was an expert of all things computery), i have after a lengthy and in depth process (dragging the pinterest button into my enabled services ! ) a pinterest button on my page ,Yay.
