Stamps can enhance the look of your soaps quite dramatically.
The right stamp and maybe even a bit of gold mica can make a swan out of an ugly duckling.
Experience has shown, that stamps work best for hot or cold processed soaps. It needs a little experience to get the timing right. If the bar is still too soft, you run into the 'danger' of pulling out material when you lift the stamp. If the bar is too hard and/or using a stamp with large surfaces, you have to use a bit of force to get the result you want.
If you are using melt and pour, you might have to do a bit of experimenting to get things right, We don' t use this, so our experience is a little limited.
