Here's a simple way to make DIY durable molds using inexpensive ingredients. In this instructable i used my adjusted sticky playdough recipe.
I am making a large boquet of cold porcelain roses and was thinking of ways to make them faster.
There was the option of using silicone molds or plaster paris. However, I was a bit unsure how safe silicone was to handle and plaster paris usually ends up pretty messy.
So I settled on sticky playdough. This sticky recipe picked up all the finer details from the leaves I was casting. And the resulting leaf impressions were surprisingly clear.
