Thoroughly wash jars with soap and hot water and let them dry completely before using.
Working small sections at a time, apply Mod Podge to the surface of the smaller 8oz jar.
Gently place one pressed hydrangea on top of the glued area and press down.
Seal the hydrangea in place with another coat of Mod Podge over top.
Continue adding one pressed hydrangea at a time on to the glass, overlapping the other flowers for more coverage. Cover the entire jar and then leave the glue to dry fully.
On the larger 12oz jar, paint the surface in a soft purple acrylic paint. Let the paint dry fully before proceeding.
Tie a piece of twine around the neck of the jar and fill jars with candles, flowers or candies and enjoy.
