Leather Glass Jacket

posted by Matt Pierce on October 17, 2012

Yes, I hate the word koozie. It's a horrible term. However, sometimes you need some insulation on your burning hot coffee cup as to not squeal and throw your full drink after picking it up, and there's not many other words that come to mind. For this post, I'll still call it a jacket out of principle.

I like using half-pint mason jars because they are easy to find, inexpensive and easily replaceable. Classic look and a good size, but not good for hot drinks. Here's a quick way to save your delicate hands and make something fun too. I put a quick lesson together over at Design*Sponge with the full details. I talk about some new tools, and if you're wanting to do any leather crafting, they are a few that you should own.

Have a look, and maybe you'll want to give it a try. The techniques can be used to jacket plenty of other things too... beer cans, tennis ball cans, yogurt cups, tobacco tins?

Sorry Aaron, I’m not taking any commissions these days.

I made a really ugly version of this one morning when I realized I only had a stainless steel water bottle to carry coffee in. I covered the bottle in a wide strip of leather and glued it together. The stitching is a much nicer idea. :)

Can I commission one of these for a Mason Jar?

I made one of these for my wife’s Mason jar coffee cup a few weeks back. Works like a charm.

Hey Rachel, thanks so much and sorry for the late reply. A lot of great tools can be had at Oregon Leather Co and the thread we use is waxed linen.

hey matt,
first off, i really enjoy seeing your projects on here and via instagram. i love the work you do and the simplicities of life and creating you enjoy and share. beam & anchor is one of my favourite spots.

i’ve been working with some leather lately…just made an eyeglass case and was wondering where you purchased your leather working tools? would love to support a local shop or products made in the usa. also what type of thread do you purchase/use for your handsewn designs?

thanks in advance for your help!

i love your work!!

MMP on November 14 2014 at 10:22AM

Heh, I like how you called it really ugly too. If anyone could stitch a good looking one up, it’s you!

Strange – I just bought a sipper lid from for a mason jar. Your sleeve project is on my list when I can find some leather and appropriate tools. thank you
