Visit this shop Al Aziza in Souq. They have lot of varieties in terms of fabric and quality. The sales guy will send someone to ur house to see how much fabric is required and will himself offer u the best price. They will also do the stitching. I went to Najma before this and they try to loot u in best possible way. Their price was two times higher for a very normal type of fabric as compared to Al Aziza.
