Mason Jars are great for toting drinks or snacks on picnics but I have broken a couple, even with careful use. This is a pattern for a knitted and felted cover for a quart size jar. It will prevent breaks and insulate the contents. A handle makes the jar easy to carry.

This version is color blocked for a bit of style, but you could make a solid one or use your stash and make stripes, just be sure the yarns you use are all feltable and that they felt at the same rate.

This individual pattern can be purchased through Ravelry or as a part of my ebook, Handwork for the Holidays.
