So, I didn't like the look of the soaps I had made in the Nutter Butter trays.  They were just too shallow and the soap didn't pick up the ridge detail in the tray.  So I tried making confetti soap again.  So I shredded some of the blue Nutter Butter tray soap and also cubed up some of it.  I made up some more soap which I colored with Titanium Dioxide to make it white in color.  Then I tossed in all the shreds and cubes and poured into a mold.  I sprinkled some cosmetic glitter over the top.  The glitter will wash off.  I cut the soap up today and it came out pretty good. 

I used a wire cheese slicer, but it doesn't cut very smoothly.  I switched back to a knife which produces a very smooth surface.
