I once talked about the famous Flower Making Tools which is a set of solder with different heads to make varied fabric flowers (especially from satin or silk).
The set of the tools is quite expensive, so many times only professional crafters use this tool set to make satin flowers.
However, beginner crafter with limited budget on craft supplies can also make beautiful satin flowers using home candles such as shown in the following video.
The process taken to make the flowers is longer than using the practical flower making tools but the result is almost the same. You can get contours on the satin surfaces with the help of the candle and finger pinches.
To try this, make sure you use a very light candle, because it can burn the fabric edge without damaging it.
