The suit can be done with a serging sewing machine or you can get a black zentai suit and glue or iron on a bat symbol but be carefull not to melt the materials if you choose to iron on. The spikes on the gloves are made from air-dry clay and glue to a piece of foamsheet that's cut along the arm. Make holes big enough to fit the spikes through on your gloves and then glue the material to the foam piece underneath. I made the cape using this tutorial: [link]. The cowl was made from cardboard and lightweight spackle. I have photos on here of the cowl's early stage. If you have trouble manipulating the cardboard look up featherweight's helmet tutorials.
