|Patterns these days are such a pain to locate on the enormous tissue paper page and then cut out without mutilating the rest of the pattern -- and still be able to fold it back up. Tricky, but I found a great tool to help.
I got a 3M wrapping paper cutter. It's shaped kind of like the handle of a plastic disposable razor, and it has a guide and a tiny sharp blade at the end. It has a rubber grip, and it works great.
Have a pattern to cut out smack in the middle of a page but don't want to trouble the rest of the page? Easy. Just use the end point to poke a hole near the pattern piece, slide the guide into the hole you cut, and follow the pattern lines. The little razor blade makes cutting a breeze. Plus, they're cheap, and if it gets dull or breaks, toss it and buy a new one!
