I always see a lot of recipes for baking in mason jars. I also see cute party inspiration for using mason jars as glasses at parties. Personally, not only do I not own that many mason jars, but I don't have enough space in my house to put that many jars out for guests. Plastic or paper cups that stack up seem to make a lot more sense to me. I do like the idea of being able to reuse them and not creating trash, but it just doesn't seem practical in a little space.
