Hooray! I just sold three of these late evening sky paintings, they'll be framed together and hung one above the other.
Just looking at this batch of 8 I did almost a year ago. I'm trying to devise  a catalog system, an inventory to  keep track of my paintings so each is numbered and  named. i.e. these are "Lavington skies with Jet Trails" (no's 1- 8) but 81-88 in the  main list. Does anyone recommend a good system of cataloging?

And it was whilst doing this series , some differ slightly in size, that I realized I had to make a better effort at standardizing sizes so bought  a big batch of ready cut board, all primed now and ready to go.

Evening skies with jet trails over the village of Market Lavington

These eight paintings were done "en plein air", sitting in the tailgate of my car, at the end of May into June 2011 (posted some then). Some were done on consecutive days within about two weeks, when we had  a beautiful period of calm warm weather with still evening skies. Practically there were always jet trails hanging motionless, or being drawn across the sky as I watched. Sizes are 8" x 5" in the main thought the first three were of slightly different height sizes, using offcuts, till I realised suddenly that I should standardise sizes and create a series.
Now I'm trying to decide how to display them, in groups of three, or four or singley. I quite like the set of three or four as it gives rise to the idea of 'time passing', and possibly 'film', that almost old fashion medium (with sprocket holes), much superceded by video format.

 One has to work very fast  to get the paint down as the sky is changing swiftly all the time. So these probably took half an hour on average . It is really difficult to be sure as I always forget to check the time. Sometimes I'd get there and wait a bit  to summon the energy; sitting, contemplating  till it  felt 'right' to start (better late then never), sometimes weary(or lazy) and mesmerised by  the splendour and drama of it all. Then urge myself into action working, against the clock to beat the fading light, till I can't see the colours I'm mixing - it can feel rather futile trying to attempt this.(once or twice I didn't even get going)

  Often I'll  listen to music a walkman, Bach piano sonatas/partitas are good, they seem to stop out other thoughts and interruptions, helping  the mind (and paint) to flow -  the melody lines interweaving, stir feelings and energy, somehow relating to interweaving evolving cloud patterns.

Top of Lavington Hill - in progress

Oil on canvas 20" x 16" Working on  a larger format, 'en plein air'.
The edge of Salisbury plain, looking West, with strange light/colour effects in the sky ..... There's  a also a compositional challenge here ... I wanted to convey something of the richness of a roadside verge, some sunlight  hitting  a patch of brambles etc.. Below shows the progression of the work.

Garden study with sundial, and yellow roses.

The lovely roses were just gone over with petals dropping but enjoyable to paint.

VIEW OVER THE LAVINGTONS, WILTSHIRE

View over the Lavingtons from Strawberry Hill. Capturing something of the unprescedented warm weather this April. A three week gap between starting and finishing this one. In the meantime all the foliage and rape seed had grown so had to update with a lot of colour. You  can see the two church towers of both villages

 Painting in progress. It was completed in two sessions.
