Great pourable spout for any size Mason Jar. Great for anything from hot cocoa mix to homemade coffee creamer or sugar.
This is pretty self explainable, I used the most important pictures to show you how its done. The Pin I found it on only linked to the photos so I’m sorry there’s no link but this looks pretty easy to do.
Simply use the lid to draw the circle around the lid to the size you need, they off set the spout so it would be easier to pour.
