Please explain why you see the need for molds on the bottom. The layer of already poured blocks below work as a mould bottom as they are just poured seamlessly on top and next to each other.

As we only need molds on the side they don't need to carry the full weight of each block. Try to calculate it yourself. Near the bottom, the force on a 10cm long strip of 1cm height on a flexible mould side would be the weight of a stone column of 10x10x100cm. That would be about 20 kg for limestone. That force created by the weight of 20 kg then spreads towards the 4 sides and the bottom, so we need to divide it by 5. That means the equivalent of about 4kg would push out on a 1cm x 10cm long strip on the bottom. That's not much for leather or similar stable fabric. Please note that my calculation is a really rough and most likely not precise one, but helps to understand how much the weight is distributed in all directions.

That photo shows the famous cutting traces at the north western corner near the 2nd pyramid. Davidovits talks about that at minute 8 in this video: [www.youtube.com]
