Moldy trim

Just a quick note on how I made my trims for the bookcase. I had purchased a brass trim which was going to prove difficult to attach and besides I didn't have enough of them so I made a mold from a two part silicone product purchased on Amazon. This two part molding product is quite expensive but for small projects it's great because the amount of detail achieved is wonderful and it's easy to use. Once the mold set after 20 minutes I pushed some air clay into it and put a piece of plastic packaging over then used a roller to squash the clay well into the mold and force out the excess. The 'positif' trim tends to stick to the plastic so when you raise the plastic it comes with it which is good as you can put it aside to dry as is without taking it off. If you have enough plastic you can repeat this and leave as many as you make to dry each on their own plastic bed ! When dry you can trim off the excess and paint them or in my case gild them with gold leaf before patinating them. 


  1. Hello Mrs. M and Thank You! I have recently been making architectural dollhouse trims using molds as well but I never thought to use a piece of plastic to help release them from the molds, which is A Perfectly BRILLIANT idea!
    I currently have a pile of fragments but now I shall be giving your technique a try and hope to have better success! :D

    1. I made two more molds today but didn't take my time and they have to be redone! I must learn to sometimes go slow ! If you use this technique you should trim off the excess clay when its soft and Don't do like me and wait until it dried completely !

  2. Ingenious method and one that I, too, will employ in future experiments! Where were you last year when I had to make all those roof tiles?!? :O)

  3. God I hadn't thought of roof tiles yet ! How did you make yours ? I was thinking of making stone slabs for the hallway entrance and thought of using card smeared with wall filler, what do you think ?
