The most important part for any sample request is the hand over from you to us. The more you information provide the faster and easier (& cheaper) it will be to produce the samples/collection that you are after making. Maybe you will send us the actual shapes to copy, or web links to others designs with notes on changes required or spec sheets. We charge 2 X estimates wholesale for simply designs and if more complex an additional $50 per style that we hold as a bond until the order comes in when we credit you back.
We are not a fabric supplier but know where the suppliers are & what they hold in stock. By far the best supplier in Bali is called Warna Jaya (also Silky Jaya) here http://warnajayabali.com. They hold around 1,500 different fabrics in stock, such as cotton, Rayon, Linen, Silk and plenty of blends all easy to browse in their office in Denpasar. If you're coming over to Bali they should be your first point of contact & do remember to request the the swatches of your chosen fabrics, showing us the code and name and the costs of each one.
If your not coming over then be aware that we cannot send out runners to search for your fabrics as the choice is too diverse. You will need to know whether the fabric is woven (like shirting) or knitted (like T-shirts) or better still some locally sourced swatches of fabric for us to match.
