This has definitely been done out there on the internetz. But I needed some tiered cake stands for this upcoming shindig and I didn’t want to spend a bunch of money so I made them myself. I think my grand total on four sets was $25, which is the usual price of just one. 
Make sure you clean everything well before you start. You’ll need some plates and some vases or glasses.
I have this silicone adhesive that’s leftover from my failed Kintsurokoi experiment and some carbon-silicate sandpaper from my glass-cutting exploits (I never throw anything away). 
I used the sandpaper to rough up the areas on the plates and glasses to which I’d be applying adhesive.
Then I carefully applied large amounts of silicone adhesive to the rims of the glasses I was sticking down. 
And ever-so-carefully plopped them on the plates. You might want to measure where the centre is. I eyeballed it. But that’s my style.
And added more plates. 
I followed the instructions on the adhesive (you should always do that) and let it cure for 24 hours.
They’re going to make great little treat stands!
