Go on ebay, and search for 'organic flax oil'. Make sure it has no additives. Compare prices, make your choice, and order.
Get a couple of empty jars with screw top lids while you're waiting on delivery. Wash them in very hot water, and drain.
When your oil arrives, pour it into your jars until they are about half full. Add a generous amount of salt to each jar, then top up with water until they're full, and screw on the lids.
Shake the jars vigorously, then put them on a sunlit window sill. Shake them once a day for about a month, then whenever you remember when you pass by them. Leave in the sunny spot for a year.
When summer comes around, buy a turkey baster syringe. Use it to remove the oil from the jars and put it into a plastic tray, such as is used to hold seedling pots. Put this tray back on your sunny window sill, and partially cover with a sheet of glass or perspex, leaving a gap for air. Once in a while, whisk the oil in the tray with an old fork kept for this purpose.
You will notice the oil getting thicker over time. When it has reached a treacly consistency, pour the oil into small glass jars and seal them. Congratulations: you have stand oil.
This will make a fine painting medium when mixed with turpentine or mineral spirits.
