of the cups, what do most of you use, is it coffee filters, brown paper bag or vacumn cleaner bags or filters ? also when you glue your bottom on the cup, do you trim off access or do you leave it on ? do you guys leave your powder paint in the cups all the time ? Just got my cups cut and now getting ready to put the bottom on them.


Sorry for all the questions, this is my first attempt at making a fluid bed




Thanks
