The type of clipart that I use is important for all of the different effects that I'm creating. It needs to be a vector drawing for sure, as non-vector drawings are bitmaps that don't resize nicely... they'll just get all bumpy and not look good. Also, I'm drawn to simply line art because if it's too complex sometimes it doesn't look as good in the different sizes. It's also good if it's a single color, usually black, because then I can change it to whatever I want quite easily just using simple graphics software. Just remember, simple is better, is cleaner, and usually creates a more sophisicated look.
Scrapbooking is a fun and popular hobby. There are new techniques and products introduced all of the time. Many folks love to browse craft stores for just the perfect scrapbooking supplies, while others are happy to search the internet for the wonderful freebies available now days. Why spend a fortune of scrapbooking goodies when you can find many of what you need with a simple Google search.
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.
