Approaching Lemon Street Gallery one morning in January, I had a feeling that Morag Ballard’s first solo show in Truro would surprise and delight me. I was not disappointed. The pristine white walls of Gallery One provide the perfect backdrop to her striking artworks. Spare, clean lines on curved boards or undulating surfaces induce a feeling of calm, while reliefs and collages set out to tease - and challenge - the eye, oscillating between the two- and three-dimensional. Geometric form takes precedence over colour, yet the shimmering hues, meticulously applied, imbue the canvases with a lively rhythm.
