I'm not a fan of the crop-a-dile. I've used eyelets for year and all i use are these little eyelet setter things and a hammer. I find that option a lot more versitle for my purposes, though since you're working with vinyl, the crop-a-dile might be better for yours.
Here are a few of my more recent scrapbook pages. They're from my senior year or college and are all from different traditions my school had. Unlike a lot of scrapbookers I don't do pages with one picture on it, and I always find it difficult to find inspiration because while there are a lot of beautiful pages out there that people have done with one or two pictures, I prefer to have more pictures and less embelishment. So here they are hope you enjoy them!
(the tiny robe on the page is painted as nearly exact replica of the one I wore for all our traditions.)
I've used newspaper articles in my scrapbooks before. And I just pulled them to check on how they look. So far it appears that they haven't fadded at all or yellowed which is what usually happens due to age.
I would say however that you should be careful how close you put them to pictures, as people have already mentioned the acid in the paper can cause pictures to deteriorate. From what i've heard they yellow and fade, which is why most scrapbooking stuff is made to be acid free. All of my newpaper clippings are on seperate pages from my photos so i can't tell you first hand.
I've used 1940s/1950s life magazine clippings in collages i've done, but I generally use kind of glue heavily on them so they don't tend to change since they are mostly sealed.
here's my nature themed can that i sent to yarn_tart!
there was no can because i left it in the office and forgot that the people i share it with were coming back, and it got thrown away by one of my neat freak fellow SGAers. But i'm thrilled to know you liked it!
