Today I'm going to show you how to make a flame on a weapon from green stuff. It will be useful to give this extra magic look on a special weapon wielded by your heroes. We will need a plastic bits, a sword works best. Some green stuff, lube for the green stuff I use hand cream and a sculpting tool.
The first thing you do is prepare your bits to hold green stuff much better. You can rough it with sand paper or a hobby knife. Be sure to do it only on the places that you want your flames to be.
Roll some green stuff and make some triangular shaped cones which will be the base for our flames.
Put the cones on the rough spots of the sword with the wider end. Put some cream on it and with delicate moves flatten it a bit with your fingers. Let it harden a bit for about 20 minutes
After that shape your flames with the sculpting tool by making ridges in the triangular shape. When making ridges pull your tool towards the sword. Now put some cream on your hands and curve the flame at its top.
Here is an example of such flames made by me on a model that I did long time ago.
