You need to go to a better hobby store . What I believe Chris was reporting about (and I've talked to him in person several times at launches and seen what he's using in his rockets) is something like "Micro-Cut Aircraft Grade (Birch) Thin Plywood Sheets" from Midwest Products Company (https://www.hobbylinc.com/htm/mid/mid5244.htm), not the crummier stuff one sees at places like Michael's. But my point is that once you get as thin as the 1/16th the OP was talking about, you are looking at a major loss of strength, both absolute and directional, even for the best grades of plywood available.
Bought a lot of plywood--Midwest is especially bad. Yes, have aircraft grade with birch veneer, but beyond that lite-ply poplar. Really weak stuff.
