Pour Spout Mason Jars
When finished with an empty cardboard salt container, cut the whole round top piece off and measure to fit a canning jar ring. Trace and cut with the flat part with scissors to fit a pint canning jar. Fill the jar with sugar, then cut a second one from a second empty salt container for non-dairy coffee creamer, spices, or flour. The pour spouts make for easy access to your sugar and creamer.
*If desired, half pint jars can be used instead of pint jars.
