Making Lamps with Material?

I'm looking for some help on making lamps from material. I recently saw them at a craft show. I thought I had it figured out but I'm wrong. They used an electric candle light. like the welcome lights you see in the windows of houses. I know they attached the candle base on a block, wrapped material around the bottom about half way up the candle. I thought they used fiber fill to make the material look puffy. I tried fiber fill but it made it look lop sided so that didn't work for me. Does any one have any idea how they're made?
