WHAT?

We have a walled garden with several trees growing along one side; we let this area grow fairly wild, and I love looking at the old stone wall under the trees. Here is a photo of one small section:
I liked the lichened trunk against the lichened wall, and decided to try to paint this using some of the techniques I tried in the online workshop I attended through OCA with Clare Wilson (see separate blog post in April 2021), although this time only using Cobra water-mixable oils.
SO WHAT?
I chose a primed board first of all (24 x 30 cm). I wanted to use collage, and prepared some slightly creased packing paper from an Amazon parcel as the paper I would tear up. I put a couple of blobs of each colour of my chosen palette – raw sienna, burnt umber, cobalt blue and titanium white – onto a glass plate, rolled over them back and forth with a roller, and then printed onto the packing paper a few times, rubbing into the back with my fingers to add texture:

I then covered the white of the board by wiping off the remains of the paint on the roller:

First rookie error here – I tore up my sheets of collage paper into the shapes needed to indicate the stones of the wall, and then tried to stick them on with PVA glue. Somehow I thought, because the glue was water-mixable and the paint was water-mixable, that this would not be an issue. However, the packing paper, being unprimed, soaked up the oil and was very reluctant to adhere to the board. I left it overnight, but had to apply more glue the next day to achieve some sort of bond:

I thought I should leave it over another night in the hope it would set into some sort of workable surface, and used the time to do some sketchbook drawings – a blind continuous line drawing and some detailed studies:
I wanted to go for a suggestion of tree and wall rather than a photo-realistic image. I began with the tree, blocking it in using a wide flat in dilute raw sienna, before working in some burnt umber and cobalt, finally adding a little white mixed with a touch of raw umber for the highlights at the edge of the trunk and the lichen. I darkened the shadow on the wall behind the tree with some umber/blue strokes applied with the edge then dragged with the flat of the brush, and added a couple of shadows under stones of the wall in one patch in the same mix, just as an indication.
I came a bit unstuck with my indications of leaves. Due to time constraints I had made another rookie error – skipping the making of a colour card. As a result my green which I could mix with the sienna and the cobalt was a tad sludgy, and not improved with the addition of white (even sludgier). I decided to add another yellow to my palette – I thought my lemon yellow would be a bit garishly bright, so went for the Indian yellow; I mixed this with a little blue and white very loosely and just applied some streaks with the edge of a palette knife. I think this just lifted the painting a little, it would have tended to the unremittingly gloomy otherwise:

NOW WHAT?
- This is clearly not an archival painting – the thin packing paper will succumb to the oil paint and start to disintegrate.
- Despite this, I am glad I did the experiment – the printed collage made for an effective textured background to contrast with the painted-on tree trunk.
- I am also glad I made the decision to add another yellow to my palette at the last minute, and to choose to apply this impasto with the knife to add yet another texture.
- I do feel I have captured something of the secretive nature of this little corner of the garden, without letting it become too gloomy.
To repeat this technique, I would consider finding another thin paper (maybe a robust tissue paper? – I’d want something which would tear to give satisfyingly ragged edges) and coat it with a dilute layer of gesso before printing onto it, in the hope that this would stop the oil absorption and allow for better adhesion with the PVA.
