Below is a calculator to help you mix just the right amount of Ecrylimer for a mold. Our mould range can be found here.

All you need to know already is the volume of the mould you wish to use. You can get this 3 ways:

  • Fill the mould with water & then tip the water into a measuring cup - the volume it fills to is the volume of your mould.
  • Place the mould on some scales & zero the scales. Fill the mould with water - the grams displayed = mls of water.
  • If you purchased your mould from B&V we have the approximate mould volume on every listing.

Our Story

B&V are Sarah & Cody, two women based in Regional Victoria, Australia. Creating colourful & cheerful things has always bought a smile to our faces & it's a daily delight to be able to help others create those things too!

Shaking up the Shape Cutter scene in 2019, offering modern shapes in fresh colours but most importantly: sold individually. Most cutters back then were sourced from internationally based, traditionally focused printers & had to be bought in large sets of sizes that weren't always right for slab earring making.

In early 2020 we made the exciting decision to grow into
your one-stop-shop for Earring Supplies, focused on contemporary polymer clay making. 

Now in 2021 we're working super hard behind the scenes to continue to grow that range & bring some exciting new things to the table (helloooo resin!).

We would like to thank you all. Since June 2020 Blackbird and Violet has made monthly donations from our sales to the groups below. Cumulatively we've given over $27,000 so far and are proud with your ongoing support to keep this total growing.
