My DIY mason jar travel cups. Super easy! All you need is: 1.Small or large size mason jar-(Michaels Crafts) 2. Rubber grometts size 3/8 inch (Home Depot) 3.Thick plastic straws (Michaels Crafts) Using a drill, drill out a hole 1/2 inch thick in the center of the mason jar lid. Insert the rubber grommett, place in your straw, and you are set! This is for LeeAnn!!!!!!!!!!
