A faux funnel like this, sugar_soap? Yet another technique to try, I will never get to all my "to-trys". I came across a nice wispy ITP swirl that a nice Dish poster was kind enough to give directions for, link is below the funnel link if you are interested. I kind of liked the look of it b/c it seems like something you could do with a tricky FO and it would be quick enough to still produce a nice swirl. Directions are about 3/4 way down the page.
