Ok, I have written out the pattern for my no side triangles Garterlac Dishcloth. It is in .pdf and you can download it here. I am also going to put up an icon in the sidebar with a link to the pattern.
Now if you have knit a garterlac dishcloth or even something in Entrelac, then you will know how difficult it is to wrap your head around not having those nifty side triangles. It took a bit of experimenting, but I think that I have down a pretty easy pattern for it. So, if you want something a little different for your washcloths, check it out!
