The Mason jar has had a resurgence in popularity as of late. Gone are the days where its sole destiny was to sit on a root cellar shelf, collecting dust and protecting peach preserves. We’re seeing creative folks make all kinds of clever things with the iconic glass jar: snow globes, amps, wall-mounted storage, chandeliers, radios, terrariums, Rube Goldberg machines, and more.

Enter your canning jar projects in the Mason Jar Challenge for a chance to win an iPad Mini, a bottle cutter, a Dremel rotary tool, and a Mason Jar speaker kit. As always, we are looking for superb documentation, originality, and craftsmanship. Good luck, and don’t forget to think outside the box — er, rather, jar.

We’re happy to announce a special guest judge for this contest, Jennifer Fishkind (aka Princess Pinky Girl).  Jenn says:

Hi! I’m Jenn - a Bloomfield Hills, Michigan mother to three beautiful boys, wife to an amazing husband, social influencer and blogger. For almost 20 years I worked in the not-for-profit world, but not so long ago I took a leap of faith and decided to dedicate myself first to my family and then to my website, Princess Pinky Girl, and my Pinterest addiction (check me out, I have more than 3.5 million followers)!
