A piece of calligraphy usually takes a while to be created. And you'd hope that the person it's for is going to enjoy it for a long time too.
Something that can be overlooked is that not all products (papers, paints, inks) are lightfast 0 indeed there are some colours that will change if left in the light for only 24 hours (some fibre tip pens, and what we knew at school as sugar paper, for example).
I'm trying to get more disciplined with knowing which materials will last - and share some of that above.
Each of the strips of colour were cut in 2, half were kept in the dark, and the other half were hung in a south facing window which gets sun for much of the day - they were left for 5 months.
I was impressed with how lightfast the coloured pencils are, even when washed with water - a few surprises where the arrows are on the picture - especially the orange Verithin pencil because it has vanished so entirely I thought perhaps I'd missed it off by mistake (I hadn't) and because there's almost no change in the other Verithins.
Most pleasing are the Ecoline watercolour inks - I tend to use these for fun, and guessed that they would fade very quickly - but they've done very well!
I'd really recommend doing this with any materials that you know you rely on - it's quick and easy (apart from waiting for a few months of sunshine!) and might just save you from relying on a product that would fade.
