Today my yarn arrived!  I am really cheap when it comes to having things shipped, so I have to "be okay" with sometimes sloooooooooow delivery because slow=cheap.  Sometimes slow=free, and that is a really good reason to be patient.  Anticipation and all that stuff.
Anyway, the yarn for my ripple-along is  from 
Knitpicks.com.  22 different colors of their 100% wool, fingering weight yarn named Palette.  Because I am making such a large size, I thought that a fingering weight yarn would be best.  I am doing a soft ripples afghan in 23 colors (I already had 2 skeins of one yarn in my stash).  Five colors will be used six times, the rest will be used three times each (one little ball will give me 6 rows/3 stripes!).  That is a total of 168 rows, 84 2-row stripes.  It will be 24 repeats of the pattern, and approximately 72 inches by 84 inches; big enough to cover the top of my queen-sized bed with a little bit of on each side and on the bottom.  All for a steal at $51.74... plus another paltry $3.98 for the two skeins I already had but that hardly counts because it is from stash *grin*.  Still, a queen-sized afghan for under $60 - whoa!
Here are my colors:

and one sheet of my 3 sheet plan for the stripes/rows:

I am trying hard not to think about how unwieldly it will become.  It will probably be an "at home" project after a certain stage.  I guess I will find out.  No rush on this one either, but from reading most of the posts here I can see that many of you are really ripping along on yours. 
So many beautiful ripple afghans, thanks for the inspiration!
