Polyester-Marble wrapping

I tried a technique that I found on the blog andthenwesetitonfire.blogspot.com You wrap in a shibori technique, polyester or chiffon/synthetic fabrics around marbles, buttons, or rocks. Then boil it for 15-30 minutes, and then put in ice water to cool, unwrapped the texture from the tying stays permanently in the fabric. This really looked cool on their blog, check out their site for great pics and more detailed how to. I started with an assortment of chiffon scarves, tied the first one with large flat marbles, and boiled, etc...

Several of the large glass marbles did break when I unwrapped the scarf. So I used regular marbles for the next one, they tied up like a bunch of grapes. It was a narrow scarf with a marble pattern on it and I tied both ends. I was very disappointed with the results. The first scarf, all that happened was the dye came out and I lost all the pattern. No texture at all. The second one I boiled longer and let cool and dry completely before I unwrapped it. It had more texture and a white ring where the dye came out, but not at all like the blog site. The only trouble shooting I can do is try tying them tighter, boil the full 30 minutes, or try a different fabric.
