Besides watercolour and oil painting, Khalil experimented with batik. His batik combines the traditional and the contemporary. Such was the popularity of batik art that he gave demonstrations all over the world including in Australia, Singapore, Paris (Maisons et Jardins) and Germany (Cologne) in the early years. It was something he picked up by himself in Kelantan and from helpful tips by a supplier of batik dyes. He was able to infuse figuratives into his repertoire. While he did play on the cracked and crinkled effects prevalent in batik paintings, he also dabbled with using cut newspapers to shape textures as collage. Although this collage technique was first developed by Seah Kim Joo, who is now in Singapore, Khalil was working independently and separately. He had also done portraits on batik.
Khalil Ibrahim graduated with a National Diploma of Design in Fine Arts at the prestigious St. Martin’s School of Art and Design in London in 1964 (post-graduate in 1965). He turned into a full-time artist in 1966. Khalil was co-founder of the Malaysian Watercolour Society and had his first double solo of London works and Malaysian batiks at Samat Art Gallery, Kuala Lumpur in 1970. That year, he also had a solo exhibition in Indonesia, the first Malaysian to have done so. He has participated in numerous solo and group exhibitions in Malaysia, Singapore, Indonesia, Switzerland and his works have been collected by the National Museum in Singapore, Fukuoka Museum of Art in Japan, New South Wales Museum of Art in Sydney, Royal National Art Gallery of Jordan, and National Art Gallery Malaysia.
