XMAS TREE

AS I DONT WASTE ANYTHING,I HAD ABOUT 3LB OF FINISHING PLASTER OVER FROM A JOB. MAKE THESE TO HANG ON YOUR XMAS TREE.EVEN USE OTHER MOULDS? MIX PLASTER AND POUR INTO XMAS TREE MOULDS WITH A LOOP STRING ON TOP BEFORE POURING PLASTER USE MOULD RELEASE AGENT TO COAT MOULDS?? ONCE DRIED TIP OUT AND USE GREEN PAINT EMULSION SILK TO PAINT THEN HANG ON THE TREE? KIDS WILL LOVE DOING THIS TO THE RUN UP TO XMAS.PLUS IF YOUR CAREFULL THESE WILL LAST YOU A FEW YEARS? AND COST YOU PENNIES TO MAKE? YOU CAN GET SANTA MOULDS/SNOWMEN MOULDS EVEN BELL MOULDS. AS YOU KNOW I DONT WASTE ANYTHING I CAN MAKE USE OFF.??????? PLUS IT WILL KEEP THE KIDS OCCUPIED????
