Mother and mother in law

How do I politely tell my mother and mother in law to please stop pushing for things they want within the wedding trying to make the idea sound like a great option… I’m not giving much away as I any small details have said they’ve said not to do it that way and do it the way they think , I’ve stopped giving any details out, and have said we appreciate their input but it’s our wedding . We’re only doing this want and would love all our own touches representing us
