You probably know you have standard stock clipart with your Microsoft package. You click on INSERT --> PICTURE and then type in what subject type of picture category you want....and you get a few samples that pop up. But there's really not very many to choose from. Kind of boring.
Free graphics get you halfway to what you need, whether it's for an announcement, flier, or website. You love your friend, but you don't have to wait on him. With free clip art as an option for your design needs, you always have a stopgap measure. You really might need that professional-looking site or flier, but you can at least fill the space until your buddy pulls through. After all, if you are willing to take the hit by taking a less-expensive professional design route from your friend, free clipart is the next, easy step down.
