I'm Karen, a Retford-based designer fueled by creativity and armed with a Wacom Tablet.  I'm the proud founder of Costello Colours, a venture that took shape in 2023 with a simple yet vibrant vision: crafting versatile, colorful greeting cards for every occasion.  As time rolled on, my horizons expanded to include custom-printed clothing, embracing trendy hoodies and tee designs.

You'll often find me at the Retford Saturday Market every third Saturday, showcasing my creations.  My wares are featured in Wonderland Bookshop, The Pottery on the Square and The Retford Hub.

My mission?  To create goods that unite people across ages and backgrounds.  At Costello Colours, inclusivity reigns supreme; we're a LGBTQ-friendly haven.
