Hello world!
These two designs are relatively easy to make. The first design features a diamond formation of colored wool (in a random order, I put them in the order they came in the creative menu), inside a round floor of wood. The easiest way to make the diamond is hard labour, placing each block in the creative mode client.
The second idea is of a long and wide floor. It is predominantly made of quartz blocks, with pillard quartz running up near the left and right hand sides, and a diagonal pattern with lapis and redstone blocks.




Thanks for your time!
