I first started making my envelope works when I was working in and office. Envelopes would come in everyday, and leave again, in the post or the recycling bin. I would doodle and make notes on the envelopes while talking on the phone. At the time I was thinking a lot about different types of markmaking that were an alternative to observational drawing, and I came up with filling-in; the envelope interiors became a repository for meditative mark-making, working with the colours and patterns already on their surfaces. They were portable and could be worked on in transit to and from work, and at stolen moments at my desk. It was interesting to play with the idea that a drawing could begin and end according to the grid pattern being full. I began with pencils and ball point pens and gel pens, humble office materials. I made the drawings onto a variety of envelopes including pay slip envelopes, and a wedding invitation envelope.
