You might look at the original poster's blog (link in her signature in first post) to see if she posted this pattern there. The site the blog link takes you to says the blog has moved, and it looks like the new site is no longer active. HOWEVER, you can browse through the old site and see if you can find this pattern.
You might also try searching through KnittingHelp for all of this person's posts to see if she actually posted the pattern link on KH as she said she was going to.
Additionally, she might still participate on Ravelry. You can try finding her by searching for her designs (a few have specific titles as shown in her signature on first post).
If all of the above fails, you'll have to find another pattern because this poster is no longer active on KH.
