Diane Rutter, a Contemplative Fire Companion, started using the book Praying in Colour by Sybil Macbeth, as part of her journey, and found it very helpful – it has lots of illustrations, with a few bits of text and lots of practical tips.
Sybil Macbeth writes “praying in colour is an active, meditative, playful prayer practice. It is both process and product. The process involves re-entry into the childlike world of colouring and improvising. The product is a colourful design or drawing that is a visual reminder of the time spent in prayer”.
Diane used it as a starting point and then adapted it to draw/colour in her own prayers as a lovely way of intercession.
