I remember smashing down pieces of sandwich bread to be the “host”! :-) We once had a pastor in our church, who did the same thing as a child. Of course he became a priest later on to serve the “real” thing! We all learned that when we read he was coming to our parish.
Oops, I got carried away with the “post” button; sorry!
Yes, you had to smash down the plastic white bread to get the proper thinness. I’m wondering why we never used round cookie cutters to get the right shape...
