Hello! I am needing to source a clear cake base for a wedding cake I am making this summer. The cake is going to be ~20in long and 8in wide. Ideally I am looking for a plexi-glass situation similar to this . My cake will be similar to this length & width and would love to have it on a clear base.

I do NOT want to go to Lowe's or HD etc. because if they cut it for me, I doubt I would be able to clean the microplastics enough to the point of having it safe to eat off of. I considered looking on Etsy but thought I would ask the broader cake community first.

Where do you source cake bases for LARGE cakes? Arcrylic? Plexi-glass?

Thanks in Advance!
