The previous silicone mold tutorial dealt with creating silicone impression of buttons, cameo and other decorative ornaments you can put on the side of a cake. In this series, we will be talking about how to make your own silicone border mold.
You will have to choose a “solid” piece of material to make a
silicone border mold out of. You can’t use a flimsy ribbon with a lot of
holes in it as it will not leave a good impression on the silicone
mold. TEXTURE of the material is also very important so I highly
recommend materials that has a lot of texture and details but solid at
the same time.
In this tutorial, I have to use “seal-dit” to seal the materials I
am making a mold impression of. I bought seal-dit from
makeyourownmolds.com. Here’s the link to it-http://www.makeyourownmolds.com/how-to-use-seal-dit-this link is very helpful as it tells you what seal-dit does and how it affects your finished silicone mold.
To start with, gather your materials listed in this photo. I bought
my silicone from Michael’s. They sell two brands-1.Amazing Mold Putty
and 2.Easy Mold Silicone Putty.
Each brand comes with two components that must be mixed in equal
amount to create a silicone mold. Each of this box cost $19.99, I always
use my 40-50% coupon to buy this (reducing the cost even further)
The “dish” I used is made out of cardboard box top that I fashioned
into a long rectangular open top container about 1/2-3/4 inch deep, 1
inch in width, length should depend on how long do you want your mold to
with your rough bristle brush, brush seal-dit all over the border
material to be molded (including the backing if using beaded materials)
brush off/wipe off excess seal-dit, set side.
take equal amount of silicone component (I use my ever trusted
tablespoon to measure the silicone component, you can also use a
weighing scale. 1 tbsp of each silicone component will make a 1 inch
wide by 8 inch long border mold, if rope border mold with 1/2 inch in
diameter is being created, 1 tbsp of each silicone component will yield a
1 inch wide by 5 inch long silicone border)
Knead this until uniform color is achieved, work fast and precise as
you only have 3 minutes of working time with this type of silicone
1. roll your silicone mixture into a sausage shape, remember, we’re making a silicone border mold
2. lay silicone mixture into the prepared “dish”
3. flatten the mixture into the dish by pushing down on it with your index finger
4. lay your prepared border material on top of the silicone mixture
push down on the border material to embed impression into the silicone
and create a cavity, you can use your index finger to do this or you can
use the top end of your brush (or even a ball tool). if border material
have scalloped edges, use the top end of your brush to push the edge
down into the silicone. remember to work fast and precise as this brand
of silicone mold material has only 3 minutes of work time.
let cure per package direction
to remove molded border material off the cured silicone mold, simply lift one end of the material
and pull it away from the silicone mold. molded material will come off easily without any resistance

here’s a simple project I made using my homemade silicone rope border mold
the buttons on the above photo was made out of fondant, brushed with
golden bronze luster dust, all from my homemade silicone molds.
