Hi Soapbuddy. Thanks so much for the response.
A lady that I found on this forum, I contacted her via Facebook and she let me know. If anyone else is interested a seller on Ebay has them and they are a silicone mould with 6 cavities - the are light blue colour - American seller.
I did ask another person on Etsy, I advised her that I don't sell - just make for friends and family - but I was searching for about 2 months for the mould and couldn't find it (as I loved the mould) but she refused to let me know. Oh well
Thanks to Bec of Bec's Handmade Soaps for pointing me in the right direction!
Thanks too Soapbuddy - you are a wealth of knowledge and I appreciate your comments on this forum. I have learnt a LOT from you - and other lovely people on here. Much appreciated.
Best wishes
Rachael
