Oil stains anyone?

[kenshin393]

I'm looking for a way to represent oil stains on cloth what do we reckon? I work exclusively in acrylics by the way.

This might sound a bit pedantic but I suppose it depends on the type and purpose of the cloth in question. Is it dyed or in it's natural colour?
Also you should consider using oils. If you open a tube of oil paint thats been lying for a while you geet a small amount of stained oil at the lid.
If the acrylic you use leaves an absorbent finish then the oil soaks in quite effectively. You then simply add tiny amounts of colour to the oil, allowing you to vary the stains.
As with any technique new to you test it on a practice figure.
Good luck with whatever technique you use

Been trying to work with what I've got del, I had 3 parcels arrive last week. The wife's starting to get suspicious. I think I'm heading toward multiple black/brown washes with a bit of ink to give it a semi-gloss.

Could work although i've always found inks a bit hard to control.
For me they have a tendency to make washes puddle too much.
Remember if it's stains you're going for, washes might not be the way to go, stains on materials don't tend to flow but rather are absorbed into the material pretty much where they land.

One easy way to imitate oil stains in acrylics is with thinned black or very dark brown paint. Start making a stain with high dilution. After drying this will make a faint stain. Gradually decrease dilution and apply new spots within the earlier one(s), letting each dry.
By playing with dilution you can create different types of stain.

Have fun!

Thanks adrian. Thats the route I've gone down. Seems to be ok so far.

I'll second Adrian and say that I usually use burnt siena or burnt umber, very thin (oils and mineral spirits), or Tamiya's flat brown and their proprietary thinner, in acrylics. I've done as he describes, apply a little bit of the thinned paint, let it dry, then add some more. Each little bit dries nicely, leaving that little ring of color around the edges, and I adjust till it looks right, to my eye.

Prost!
