I would start by covering my ironing board with paper and give it a good press to heat set the colours and remove any wax residue if it is wax resist batik. I would then buy some synthrapol and mix it up in a bath tub of water. I would gently swish it around in the tub and see if any colour bleeds into the water. If it does bleed, give it another go in the tub and check to see if any colours are bleeding into the cream. If it is good, then dry it.
I would then use it like wholecloth panel, sandwich and quilt around the different patterns in the panel.
