Flat or Dead-Flat Oil - Provides a completely flat, oil-based finish. Generally used on walls but not suitable for areas of high wear.
Like this, it will actually take quite a while to reach a number that is close enough to the yellow color you've chosen that you can't tell any difference (and mathematically, you will never actually reach an average of 4!)
One precaution: You can't paint with it in cold weather. The chemical reaction that transforms the water solution into a durable finish will not take place if the temperature is below 50°. (Conventional oil paints don't stick well in cold weather, either.)
Which skills does play develop? Gross motor: This is the obvious area. People see children running and climbing and can clearly see that they are developing their muscle strength, coordination and balance. Parents want their children to quickly move from doing this in free play to participating in organised sports. While organised sport is good for children, if the child's gross motor activity becomes too regulated too soon, he is going to specialise in some movements (those specific to his sports) and miss out on the development of others (such as climbing trees). The more diverse a child's physical play can be, the more chance he has of developing his muscles and overall coordination in a balanced way. He is less likely to develop early tight tendons ( I see many children with tight tendons at the back of the knees) and less likely to develop weak core muscles (we are seeing more and more young children walking around with poor posture due to weak core muscles).
Hair colors come in categories of : Temporary, demi permanent, semi permanent, permanent. Each color line has recommendations on the categories and of uses of their particular types of hair colors. Each line has color enhancers, color glosses and so on. I recommend you have your stylist or colorist educate you on the types she or he will be using on your hair and why. This will help you when choosing shampoos and conditions that will help maintain your hair color between coloring services.
Fine motor: Beginning to learn to use a pencil before you have developed finger and thumb strength and stability results in a child developing an inefficient pencil grip. When a child has weak thumb stabilisers, he is likely to wrap his thumb around his index finger to try to create greater stability. This makes it very difficult for him to then develop the necessary finger isolation (separate movement of the fingers to give easy, dextrous pencil control). Children who have not yet developed their wrist stability will try to use whole-arm movements to do their drawings and writing and will press very hard. If a child has not developed the bilateral integration (this happens in the brain and is the smooth, efficient communication of the right side of the brain with the left) cutting will be difficult and he will have difficulty writing across his page and reading across a page or school board. Beginning to use a pencil too soon therefore inhibits learning in a formal class setting, rather than helping it.
You're not looking for perfection here, but you do want to eliminate every shiny spot of paint. When properly scuffed the paint should have a smooth, but dull matte finish.
