This very attractive pattern is Midwinter “Roselle”, and was produced just before the revolutionary “Stonehenge” series was introduced at Midwinter.
Contrary to what you will read elsewhere, this pattern was designed by Eve Midwinter in 1968 – Not by Jessie Tait. The design is on the popular “Fine Shape” series of forms.
Along with Spanish Garden (by Jessie Tait) Roselle was one of Midwinter’s best selling designs before the introduction of Stonehenge in 1972. It seems to be rarely found here in Australia, but is quite easy to get hold of in the UK.
The delicate border repeat pattern in blues and greens has alternating upright and inverted floral motifs on a bright white background.
The lids and saucers of the design are in a colour somewhere between Royal Blue and Cerulean Blue.
