I have learned to make sure to quilt the mug rugs, as I throw them in the wash when needed. Makes them sturdier and gives them character. My family was brought up to use a plate or napkin if they are having a sandwich, or eating in another room other than at a table or counter. For us the sandwich or cookies directly on the mug rugs is not an issue because we use a plate or napkin. It is just one of those compromises to using the mug rug for anything besides a coffee mug, cup or glass.
