Pre-glue these blocks to form the second row.However, there is a chance (depending on how you scrape the mold and stack) that the inside chamber wall would end up slightly taller than the pyramid wall.

Later on, these walls will have to match up to the sloping sides of the pyramid.Mold #96 has blocks that can be used to make a secret door.

Now the inner chamber should stick up above the pyramid blocks slightly.Personally, most people like the look of the "sand blasted" pyramid better and use mold #92 instead.Pyramid has again proven themselves to be the most reliable and friendly partner we have.
