DIY: Mason Jar To Go Cup

I first saw this DIY on Fine + Feathered (page no longer available) and knew I had to try it out! I used:
#14 stainless finishing washer or rubber grommet (a rubber grommet would probably work better!)
– glue gun
– drill or cropodile
1) Drill a hole in the lid.  It’s easiest to do this while the lid is screwed onto the jar.  (Sorry, I don’t have pics of this. My husband drilled the hole for me!)  The drill does make a rough hole. We used pliers to smash the sharp edges down.  I think you could also file them with a metal file if you have one. 
2) Use a glue gun to glue a finishing washer to the top and bottom of the lid to cover the rough hole.
 (The top washer on my cup popped off.  So I glued it back on with some super glue! I think I didn’t use enough hot glue to fill the washer before I stuck it on.)
3) Put the straw in, fill with your favorite beverage and enjoy!
Now, this is a pretty easy DIY if you can find the right materials.  For some reason I had a hard time finding re-usable straws that fit through the washers. I would buy a reusable straw and bring them to the hardware store to make sure they fit through the washers! They should be thin enough to work.
(They also only had #12 washers at the hardware store I went to and I think the 1/4 washers you see in the picture are a little smaller than what the #14 washers would be.  My husband had to shave off some of the washer with the drill in order for the straw to fit.  And at the time Starbucks wasn’t selling re-usable straws in store so I bought a child’s Avenger’s cup at Target just for the straw!) 
So other than these minor setbacks the actual assembly of this cup was pretty easy! And now I have a one of a kind glass to-go cup! (Or you could skip all the work and buy a pre-made lid or jar with a straw!)

    We JUST got into using mason jars recently. Good for saving soups and putting together yogurt parfaits for work. And they are adorable.
    This is such a clever idea. I need to get a hot glue gun, it seems.
