Presently I am using a cheese planer/slicer to bevel the edges. Does anyone have a better idea? Finishing the edges takes it up a notch, especially when colouring doesn't work out as planned.
Milk cartons
I mold all if my soaps in milk cartons lined with parchment paper. It works very well and fits up to 2 lbs; no leaking, spillage and I am recycling at the same time.
