Have you seen that Ball has produced blue canning jars in honor of their company's centennial celebration?
I bought a box of 6 of them at Target, and decided to make them into summer drinking glasses.
It's easy peasy to do!
I followed these instructions.
I put the lid on an old jar, (so if the jar broke I wouldn't be sad),
set the jar on a firm surface, and holding the jar still with one hand drilled the hole using a 3/8 inch drill bit.
It worked fine and the lids didn't buckle.
I bought 3/8 inch neoprene grommets at Home Depot.
It takes a bit of work to get them all of the way in the hole,
but using a stiff plastic straw from a Starbucks cup to help push them through worked for me.
Really cute for outdoor suppers on the patio, don't you think?
And it's my favorite kind of project, cheap and easy!
