Hand Molding!
On week six Thursday, we done some hand molding for this it might be a bit hard to do if u don't have a certain ingredient (cant afford it maybe)

for this you will need:

-A tray.
-Sand.
-concrete mix.
-water
- something to hold the concrete mix in

Now what you do is:
-grab your tray and your sand, and then put all you sand in your tray about just over half way
-now put your hand on the sand and press it in as deep as you can.
-now grab your water and concrete mix and slowly pour water in the mix bit by bit while mixing.
-Then let it dry
 this while take at least a day to dry properly.
