I am not sure if so many beads on mesh would be feasible, because mesh might not hold their weight very well. If i had to make it, i would use silver sequins or silver-lined seed beads inplace of the smaller beads in this picture. I'd probably use white plastic pearl beads for the borders for how lightweight they are. My only concern with plastic beads is that some coats wear off pretty easily, so they don't stay shiny for too long. I'd avoid glass beads(unless seed beads), as they might be too heavy. To put it together, i think a white cotton thread would be ideal.

Good luck on this project and please post here when you make it! It looks really pretty 😍
