Holly comes from the creative family of Alec George WALKER and his wife Kay, who established and developed the Crysede design company that produced printed silk garments in the 1920s and 1930s in West Cornwall. Alec and Kay were her grandparents, and though she works with ceramics her inspiration, like theirs, comes from the natural beauty of the Cornish countryside.

In 1977-8 she worked as a decorator at the Troika Pottery, but has since then set up and worked from her own pottery in Penwith (Kelynn Pottery).
