you should be able to put the rubber or felt sticker things on the little feet.. the felt ones are usually green circles.
or if you have anything around the house,you can just cut and glue to the bottom legs/pegs. maybe ever flannel would work!
i need a new crockpot..my SIL bought a hamilton beach..there is one on the market now, that has a locking lid..so if you take it to a function, it won't spill,or the lid will stay on!
