towel, large flat surface with plastic or newspapers on it, lots of newspapers, iron, water supply, electric frying pan (dedicated to art), soy wax, fabric paints, things that make marks like potato masher, cut out sponge shapes, egg beater, cardboard tubes, paint brush or soft sponge, fabric to batik.
I used a purchased silk haboti scarf 8X54. Iron it first like I didn't. Start the electric frying pan and add soy wax - flakes not a solid chunk. I set the thermostat at about 150 degrees F, just hot enough to keep the soy wax liquid. Soy wax melts at a very low temp and washes out of fabric with a simple hot wash (more about this later). I wouldn't use nor recommend any other form of wax.
I covered my work surface (a 2'X4') home made ironing board with 6 mil poly film and plain cheap felt.
I made this ironing/silk screening/monoprinting surface out of a 2'X4' piece of 3/8" plywood from Home Depot. Cost about $8. I covered it with felt and 2 layers of warm and natural batting and a medium weight muslin fabric secured with a staple gun. I set it on collapsible horses ($12.) This surface is the BEST tool I use and I can collapse it in 30 seconds if needed.
I used a potato masher (they come in many shapes so get a variety) and set the end in the hot wax for about 30 seconds to heat the metal, shook off excess wax and applied in a pattern to the white silk.
Next I used some fabric paint that I thinned with water. You just need to try it yourself, get a feel for the consistency you like best. I started with paler colors since I would be adding 3 colors on top of each other. I applied the first (for me the lightest) color using the small square of soft sponge and put the scarf on a drying rack to dry in front of a fan.
Above, you can see the potato masher imprint. The first color paint was light lavender. Dry completely between applications of wax and paint. I used this rack. The next tool I used was an egg beater and a metal bit from a lamp I threw away after scavenging any interesting parts that would make shapes!
This is much better looking in real life. It started to storm here and I lost the light. Both are habotai.
