How to Make DIY Mason Jar Cups

Do you have shelves of mason jars?  I do!  I love them and use them for so many things from hanging lanterns to party decoration to sweet little gifts to food storage.

They are inexpensive, fit perfectly in a cup holder, come in tons of sizes and get them in blue, green or clear.

If you want to transform your mason jars into drinking cups it literally takes minutes and about $.50 to do.

You just need a few things to make these cute little jars:

• Drill or Hole Punch
• Mason Jar with standard lid
• Rubber Grommets from the Home Improvement store
• Straws

And that’s it!

So you want to put a little hole in the lid of your cup.  If you have a drill handy you can screw the lid of the jar on and that will provide a base to drill.  Carefully drill your hole in the spot you like (the center or side).  We drilled on the Ball logo each time so all the lids would be the same.  That is a good idea if you plan to use these at parties and such. You can also use a Sharpie to mark the same spot on all your lids so you drill in the same place each time.

You might want to sand a tiny bit if you have really jagged edges around your hole.  I didn’t need to bother with it because our hole was pretty clean.

And I am sure it goes without saying to wash the jar very, very well after this as there are lots of little metal particles and such.

If a drill is not handy, you might have luck with a hole punch.  We have the 3 ring hole punch and my lid wouldn’t fit but if you have one of those single ones I think it might work.  (Worth a shot).   I haven’t tried this but I have used a hole punch for thick cardstock so I am thinking it might give you exactly enough space to slip a straw through.  You would probably not be able to get the rubber grommet to fit. 

Next you have to zip over to the home improvement store.  I can’t recommend taking your lid and a straw with you highly enough.  (Said from a person that made two trips to Lowe’s for this simple project.)  You want to head over to where they have screws and nails and such and ask the employee to help you find small rubber grommets.  At both Home Depot and Lowe’s they were located in these huge pull out drawers and I want to say mine were about $2.00 for a 4pk.

Once you get those little guys home, just squoosh them and squeeze them and they should fit perfectly into your hole making a clean seal.  And now you are all done!  See?  Fits perfectly!

I soaked my grommets in hot water and soap first to clean them but you can also just rinse your lids after you make it.  I like to hand wash mason jar lids anyway.

And now you are all set to have an awesome cheap and cute and functional mason jar cup.

I have seen people spray paint their jar lids or paint the jars (on the outside).  Personally I wouldn’t paint something that I would be drinking from but totally up to you with what your comfort level is.

For my cups I used the Blue Heritage Ball pint jars you can find here.    They also make green jars that are really pretty- you can order them here.

I also used the new Blue Mouth Jar Lids here- these also come in green.

If this seems like too much bother for you, another option is to buy the sip and straw lids here and these work just the same or the Cuppow lids here.

And I like plain disposable straws but if you’d like to pick up reusable straws there are some awesome stainless steel ones here.
