Advice on cutting in please?

I almost do a little dance when a bristle pops out of one of my Woosters-it's that rare an occurence.

 

when cutting in it best to have at least one coat of paint applied to area before you even try to start cutting in
why you may ask suction drag from the old (bone dry) paint covering as your hand is straining to pull or push the brush.
so when you are painting your ceilings dont cut them in to the ceiling wall junction paint both ceiling and wall bringing the ceiling
paint down onto the wall by the size of your brush.
if your wall color is very light one coat of paint cut in to the ceiling should cover.
if you have contrasting colors don't try to fine cut in the first coat of paint just keep your brush well loaded and fast cut approx 5mm bellow the ceiling thus stopping any suction drag when you fine cut.

LOADING YOUR BRUSH.
before you even start to paint give your brush a quick rinse with water/thinners depending on type of paint finish and spin dry the brush between your hands, this will stop your paint starting to dry inside the root base of your brush causing the brush hairs to splay outwards or clumping together refusing to let your paint flow out smoothly.
next 1/3 fill your paint kettle and start donking your brush well into the paint without getting the metal strap joining your brush hairs to the handle covered in paint as that is where your fingers will be holding the brush when cutting in, when you are happy your paint brush is completely saturated with paint from tip to toe gently scrape the outside of your brush on the inside edge of your paint kettle to remove all of the paint externally this will help to start shaping the brush hairs ready to start cutting in.

to load the correct amount of paint for cutting in donk the brush 40mm into your paint kettle making sure the tips of your brush don't hit the bottom of the kettle, remove your brush from the paint but leaving it still inside your kettle gentley slap your brush 3 times on the sides of your kettle LEFT RIGHT LEFT or RIGHT LEFT RIGHT this action will remove all excess paint but still leave it well loaded with paint, scraping the brush after loading your paint tends to leave it light of paint.
start cutting in anything at waist level first then down onto skirting boards thus giving your brush time to shape and be fully loaded again same as the ceiling wall junction don't worry if your paint hits the woodwork (painted) a little bit.
final cut wall paint to ceiling. don't plonk the brush on the wall start moving your arm in the direction of cutting in line and lay the brush hairs onto the wall like an airplane landing smoothly.
approx 20mm down from the ceiling but starting to arc towards the finale cut line, then let the brush cut a little low first just feel the line starting to form repeat this a couple of times and push your cut line upwards with each pass your cut line will be smooth and constant, don't forget to back brush where your paint brush landed firstly to flatten in any buildup.
