First, once you're finished your layout, take a picture of it and post it somewhere on the internet. (I posted specific directions for how to do this under the thread - How to post scrapbook layouts online -)
Then, once you've done that, copy the web address from the address bar of your browser. It should begin with http:// and end with something like .asp or .jpg or something similar. You can copy the whole thing by highlighting it and pressing control C (the Ctrl button and the "C" key at the same time).
Then, come to this blog and click on "comments" at the end of the post you want to comment on.
In the comment box, put your name and paste the web address you copied earlier. To paste, push control V (The Ctrl button and the "V" key at the same time.)
That's all there is to it! From there I will go find your layout and put a picture of it up on the blog so everyone can see it!
