batoola or batthoulah

Here ma question: I'm interest for the battoulah (or batoola..)I don't want buy this product but I want to know how the Qatari people fabric this, what's the technique for have this shining effect. I read an article of Qatari journal and it says, this product is don't fabric in Qatar now but in India. I'm not sure pearhaps some people know still this technique in qatar. So I just want to know for example a name of town where we can find battoulah or the technique. Of course I think that there are several techniques but it's not a problem, all sort it's important.All that can appear to you much but small information can much helped me a lot.Thank a for you answer.For you explain why I want some information I grew in Doha, and today I very interesting for the dyeing and this effect, (for exemple in China the Yunnan people, Mauritania, and Sudan, all this country use almost this effect in the clothe no for the mask but it's not really the same effect).So I hope you understand my request. I’m French so I don't speak very well in English, sorry.Caroline
