A smooth pattern making roller is a tool used in a variety of DIY jobs and projects, especially for smoothing epoxy sealants, clays, and other types of pastes. Its smooth, cylindrical shape allows these materials to be evenly spread and smoothed over a wide variety of surfaces. It is especially useful for shaping thin, even surfaces such as flags, clothing, capes, etc. If you're flattening green resin, we recommend using talcum powder and a little water to moisten the paste and achieve incredibly fine and smooth surfaces. Talcum powder also allows you to touch the green paste without leaving any traces.
