Painting knives have been used for many centuries, usually in conjunction with brushes, but you can also complete whole paintings with just knives, which are sold in many sizes and shapes.if you don’t have one, use an ordinary palette well loaded with paint for your initial experiments.
I went out and purchased a painting knife for this exercise and I initially used acrylic paint with a medium gloss gel to thicken the paint.
Also try applying paint using old plastic credit cards, set squares and protractors, pieces of cardboard windscreen scrapers and plastic plastering tools. You can apply paint quite thinly with these and lay one colour over another so that the first layer remains visible. Don’t worry about creating a painting- just enjoy experimenting.
Unfortunately I am limited to what I can find here in Bangkok but I do have an old student union card as well as protractors and set squares.
Now try applying paint with sponges, rags, toothbrushes and your fingers. Sponges and toothbrushes are good for texture effects, and can be built up in layers or laid over flat colour. Rags and fingers are useful for blending one colour into another or wiping across the surface. This exercise is best done with oils as they dry slowly, giving you plenty of time to manipulate the paint.
I went out and bought a small pack of oil paints to use for my first bit of experimentation. I had some board that I have been using for backing board for my first assessment (drawing 1) so I decided to use the oils on that. I had learnt how to clear my mind and doodle in Drawing 1 so I decided to continue here.
I started with black and white paint with a painting knife which I didn’t think was as controllable as I thought. I thought I would have more fun with this. I used the knife on the bottom and forgot to prep the support which seemed to absorb the paint so I covered the rest in Gesso.
Next I used my old student union card which I found was more controllable than the painting knife and that I could get better angles (flatter to the board) with it.
This was the first time I used bubble wrap which I wrapped round a Vicks’ Jar to give me almost circular groups of prints with it. Later would use a soap box which gave me a large square of prints that was better for covering bigger areas.
I have yet to find a natural sponge. I did used a synthetic sponge on it which gave me the same texture as a cloth.
I loved using the protractor but I found I had to either put loads of paint on it or move the protractor in a wave like motion on the surface so that the whole edge would touch the surface. By then dragging this down I could make a fan like pattern.
For me that was my first bit of oil painting done and what I learnt from it was that I had to learn how to mix better so. So from there instead of wasting more oil paint I decided to continue with the acrylics and medium gloss gel instead.
I had seen how these looked together separately on the same support now it was time to see how they could interact with each other and so the next ‘doodle’ was a result of finger painting over painting knife and then bubble wrap and protractor over the top. This tyime I made circles with the protractor.
Reading the brief again I realized I had overlooked the toothbrush, so with a flat toothbrush I set out to recreate the same landscape I attempted in the last exercise, Getting to Know your Brushes, personally I prefer the toothbrush landscape below
Bubble Wrap over a Square Object
As I said above I wrapped the bubble wrap around a soap box for more experimenting, the result of which can be seen below which I tonally graded by letting the paint fade into the middle and then used a close paint colour at the other end of the paper.
My preferred painting tools from this exercise are definitely the credit card as to the paintng knife as well as fingers and bubble wrap.
