The Vinyl Fuse is awesome! You fuse it onto regular fabric and Voila! It's water/stain/messy resistant! It's a perfect idea for something like a cosmetic case. All that eye shadow dust and lip stick smudge will wipe right off! I'm imagining it on the inside of a cute lunch bag as well. Then you wouldn't be stuck with whatever ugly waterproof fabrics you can find. You could use anything! Too bad I don't require a lunch bag to take to work since I work at home. Bugger! I might make one anyway...to transport my Oreos downstairs to the Shop.

FYI: I had a hard time finding the Vinyl Fuse when I looked for it the first couple times. I assumed it would be on the Pellon Interfacing rack at JoAnn. It was not. :( When I asked a girl for help, she pointed me to the wrong stuff - which will definitely not work. You can actually find the Vinyl Fuse pre-packaged in the notions aisle. It comes in a long, skinny, orange box in 2 yd cuts. I used the Matte finish, which I liked a lot. I have yet to find it sold by the yard, although the Pellon website says it is. Somewhere. Out there.
I used a Babyville Boutique poly-resin snap and Snap Pliers. These can be found at JoAnn and many other places, I imagine. I bought my zippers (a while ago) by-the-yard from TheZipperLady.com. She has an awesome selection of zippers and pulls for even more awesome prices. I love the Pop Top pulls. I think they look cool and unique. If you have never put pulls onto zipper tape by yourself before, she has a couple great videos that show you how. It is SO EASY! If you use zippers very often, you'll save a ton by buying them by-the-yard and have so much less waste.
Anyway, I definitely recommend this pattern. I'll be making more cases for sure. Try it out, and send any questions along if you run into problems. I'll help if I can. :)
