Broken Glass?

How do I make sure I find every little sliver from a broken candle holder? (The tall stem ones)? I broke it when I was making a christmas center piece, it fell over and shattered against the table, onto the floor, (part carpet, part lineolum) over a chair. I have animals and I don’t want my two cats and puppy to get the glass in their paws.
I vacummed with a hand vacumm, and swept, but I always seem to find more glass after doing those things. (I am quite clumsy, and break things at least once a month.)
