UNIQUE! MANY USES! These collectible tools called Tjaps (pronounced Jops or Chops), have been made and used on the island of Java for over a century. They are handmade of copper strips, carefully cut, shaped and soldered into fabulous shapes and patterns. They are used by Batik artists in Java by dipping them into hot wax, shaking off the excess, and then stamping the wax onto the cloth. Aligning the edges of each consecutive stamp creates patterns which run the length and width of the fabric. Scroll down for more info and ideas. We used to sell them but our tjap hunter in Indonesia has not been able to source any more treasure troves of them for us. Unfortunately, it doesn't work for us to just offer a small handful. But you can still find folks selling one offs on the internet, particularly eBay.
In addition to wax, we ourselves have also successfully used them with Jacquard's Color Magnet, Jacquard's Resistad, and thickened dye or with thick fabric paint. Customers have reported using them to make rubbings with Shivastiks, or to emboss velvet! (By placing the velvet, pile down, on the tjap, then heating the back of the fabric with an iron) We were blown away when using them with our iCraft Deco Foils and foil glue, and they also work nicely with our Soy Wax. (make sure you wash the glue, paint, or whatever, off immediately after use with warm soapy water if you want to keep these nice, and also dry them quickly - either in the oven on the lowest heat setting for 5-10 min (Make sure you don't forget them! And have the exhaust fan on), out in the sun, or with a blow dryer as the iron handles will rust.
These are also fantastic to collect, as they are works of art in and of themselves and are so wonderful just to look at. Check out some projects you can use them for:
