My wife likes to put odds and ends of cuttings of cuttings from the garden into glasses from time to time. As usual, this one - honeysuckle in a glass tumbler - caught my eye, so I put some white card on the table, against the wall, and did the illustration from that. I covered the table top with the card because I wanted to see how painting clear glass against a white background would look. Sheer curiosity - and, of course, the glass is never clear!
