About us

Hello! Welcome to our beautiful watercolour world, we are based in East Sussex, and are proud to produce luxury greeting cards. We aim to design delightful cards featuring charming images, all hand embellished with gems. We love to look on the bright side of life and our sweet, funny sentiments reflect this.
Here at Crumble & Core we are proud to produce quality British Greetings Cards. All our cards are designed by us and taken from original watercolours by Jilly Mercer. Helping you celebrate both the everyday and the special days, we hope you will find images here to cherish and send to your loved ones.
Crumble & Core was born when three friends came together over a lovely pot of tea, (Earl Grey if you’re interested!)




Artist and Co-Founder Jilly inspires us every day with her beautiful paintings, positivity, and never ending ideas for gorgeous new cards. Jilly trained in textiles and fine art and is a Fellow of the Royal Society of Arts. Her work has been featured by several publishing houses and is predominantly watercolour, gouache and pen. Jilly’s favourite card is Fiat and balloons.


Co-Founder and commercial wizard, Lou is a Mum of four gorgeous children, no wonder she can multi task like no one else we know! Chances are if you ring up to enquire about a trade account or place an order you’ll speak to our Lou. She also possesses an amazing sense of humour and often comes up with some of the funniest strap lines. Lou’s favourite card is Lucky Pants.

Luckily for us she is now devoted to Crumble & Core, helping to develop our ranges and working with agents to spread the word in brilliant shops and stockists all around the UK.
