Longtime scrapbooker and quilter here. At Joanns or Micheals, look for a product called 'glue dots'. Use those to attach your fabric to the page. They are strong, they will hold, and they will not yellow over time. I know this because I keep a scrapbook of quilts and other projects I've done and this is what I use to hold my fabric in place. Often I use decorative scissors to cut the fabric into squares, then spread them out over the page. I would not use metal to hold the fabric in place.
If you want to go the short cut route, look for products by Project Life. They do pocket page style scrapbooking. Here's a link to a pocket style page:
http://www.scrapbook.com/store/ac-97...ect+life+8+x+8 Project Life also makes filler cards for those pages, so if you want some color without buying paper (I'm guessing you are not a scrapbooker?), this would be super easy. One slot could hold your fabric (attached to a card) the other could hold a journalling card explaining who the fabric is from.
Give a holler if you need help. I could post pics of my quilting album to show you what I do.
