If you find spinning easier with a little grease still present but your fleece is very dry after scouring, you can spray it with an oily mixture called dressing mixture.
I notice that Anne Field's original Ashford Book of Spinning (no longer in print) gave three recipes, one of which matches my correspondent's own recipe, that being:
- one part of water, one part of olive oil and a quarter part of ammonia
She says that the ammonia may not be easy to obtain from your chemist, and this may be the reason that this particular recipe doesn't appear in the current Ashford book of Hand Spinning - it keeps two simpler oil / water recipes.
pour the the liquids into a plant sprayer and shake up well to make an emulsion.
My friend's tips are to spray sparingly and to spray the fleece at least a day before spinning (but note that the mixture may become rancid over a long period of time).
