Hello! I have been rolling out my clay by hand for a couple years now but have had issues with wrinkles and uneven slabs so I am planning on buying the Bailey 16” Table Top Slab Roller. Does anyone have any experience using this? Any tips I should know? I need a very smooth surface with no texture. Is canvas best to use with this or is a slab mat better? I also need a pretty precise thickness for my work. Any suggestions for achieving the right thickness every time?
