Large Blend Help

I'm making a large blend for a My Chemical Romance concert I'm going to in about a month. The blend will be about the size of a paper. Unfortunately, I'm not too terribly experienced with blends (and I don't want someone else to do it for me..I'm weird like that). Is there a tutorial on blends anywhere? I found one by syndarys, but I'm not sure it's exactly what I'm looking for.

Thanks in advance!!
