Answer:
Materials ensure the quality of my work, while the techniques ensure my work is done correctly.
Step-by-step explanation:
Materials for me for example high quality paint increases the quality of my work, if I used cheap thick paint that doesn't go on the canvas well then it may make some areas of my painting thicker than others which is something you do not want while working on a piece. "Materials are so important because they ensure that my paintings are of high-quality material." Techniques are different ways and strategies I use when I'm working on a piece, usually I run through the same techniques each canvas because I feel that it makes painting a lot easier while making less mistakes because practice makes perfect and when you keep doing the same techniques, you learn how to do them more perfectly. "Techniques are so important because they help ensure my work is done correctly without making as many mistakes as possible."
Hope this helps.
