Directions:  READ DIRECTIONS IN THEIR ENTIRETY.  Keep out of reach of children and pets.  Wash hands after use.  Non Toxic, Non Flammable, Non Hazardous, Food Grade.
Only mix what you will use in one sitting. For a Super Flex, you will do 1 drop per 2 grams of clay.  For just a little bit of flex, you can do 1 drop per 3 grams of clay. Roll your clay out (only what you will use in one day) in between plastic wrap (I use a cut ziploc bag), with a little bit of lubricant.  Roll it out thin.  Put the appropriate number of drops on your rolled out clay.  Roll your clay up like a cigar and fold the ends over to let the drops absorb a bit.  Let sit for 20 minutes.  After 20 minutes, while still in the plastic, continuously, kneed and roll your clay.  It will seem wet at first but the flex will absorb in.  Once all of the liquid has been worked in to the clay, let sit for approximately another 30 minutes before using.  NOTE:  For the super flex effect, you need to keep your clay thin - around 2 cards thick.
