Ok,in my base,I have some shelves with cake on them,and the shelves are quartz slabs,and I live right on bedrock,I don't like how bedrock looks,so my whole base has carpet on the floor.problem:I can't put carpet under any slabs.it makes it look kind of awkward.plz fix this.

A way to solve this is by putting orange wool blocks under the slab or by using an upside down stair case as a shelf with orange wool under it
Problem,there bedrock,I can't dig that.but I can try quartz stairs.
