Oil

When I started painting I promised never to do oils. They're too difficult, too smelly, too messy an they take too long to dry. They'll be touch dry in a few days, but it takes about 70 years to officially dry because it doesn't dry by evaporation but by a form of curing.

I'm sure you know where I'm going. I decided to give it a try. I got some primer to coat the psper as apparently you can use paper!! I painted a watercolour background and decided to see if I could use that as primer to put  a swan on the water. Here's my attempt

I know it's not a masterpiece, but I will say it was fun-completely different to any other sort of paint. So if you've not tried it give it a shot, but you will need paint thinners to control paint viscosity and clean your brushes. But experiment and enjoy!
