Here is my Tribble made from tulle.
For the pattern go to: http://thingsstitchedmarketplace.blogspot.com/
I bought a roll of 6 inch by 25 yard tulle. Before I took off the plastic, I drew a center line on the wrapping and took a razor blade and cut the whole way down to the cardboard.
I don't know how long it ended up being, I just knitted until I came to the end of 1/2 my tulle. I was afraid to pull the tulle tight, but I did and it ended up looking pretty good. Not sure the cost is worth it. The roll cost $2.99, I had 40% Michael's coupon (silly to use it on such a small item, I know) and my newly 6% tax, it came to: $.95 per tribble or scrubbie as most know it.
