Here is a link to my Youtube tutorial  but if you want a quick rundown read below:

MIXING YOUR OWN MEDIUMS

 

 

The Rule of Mediums is    LEAN TO FAT.

 

 

At the beginning of the painting, use a lean medium to block in large areas and to help spread and blend the paint.

 

As you progress through the work, the medium should become fatter.

 

And finally, transparent glaze mediums are used at the end of the work.

 

 

LEAN

1 part gum turps to 1 part linseed oil.

 

FAT

 

1 part gum turps to 2 parts linseed oil.

 

GLAZE

 

Equal parts of gum turps, linseed oil and damar varnish.
