When you need to duplicate multiple measurements on a larger project, it can be helpful to use a length of 1x2 or similar stock as a story pole. Cut or select a piece that is longer than the longest cut required. Carefully mark the height, width, depth and length of various parts onto the 1x2. The story pole will speed up marking for cuts, and matching parts will be cut the same.
When starring out, pre-dampen your brushes slightly before dipping into the paint. Slightly damp brushes apply paint more evenly. When working with latex paints, moisten with water: when applying oil-based paints, first dip them into paint thinner, then pat them with paper towels to remove excess thinner.
