Dear Jacque,
I have two large pizza stones that have no carriers, either. I just
leave them in the oven until they are cool. If I need to remove them
from the oven, I use heavy oven mitts, and be sure to place them on a
heat-proof surface. I don't think a carrier is really necessary, but
you might take the stone to a metal shop and have one made. Maybe
take it to a secondary school shop class. It could be cheaper that way!
I usually only use the stone for baking pizza and breads that go
directly on the stone. If I am making bread right after baking
pizza, I put the bread pans on a rack above the stone. Your mileage may vary!
