|Large sheets of transfer paper that come in three sizes. It doesn't come off in your hands, can be erased with a standard eraser and is very inexpensive. The thing I love about it is you can get super large sizes and do very large products. I got a huge amount of it for $8.
The site says it can be used on fabric itself, but I haven't tested washing it out of fabric. I use it to trace Burda type patterns and the ones I don't want to cut (like Colette Patterns) onto paper.

The way I use it, is to lay a sheet of paper that I want my pattern to be traced onto down on a flat surface. Then, I put the woodworking transfer, paper face down on that. Next I lay the Burda down on top. Weight everything down with heavy objects so nothing moves. I use a double tracing wheel to add the seam allowance I want, and go over/roll the tracing wheel over, the outline of each pattern piece. When you are finished, cut out your pattern pieces from the paper. I like this method because I don't like squinting through tracing paper to the maze of lines underneath to trace by normal methods. This way, I can clearly see the colored lines and roll the wheel over it directly. It doesn't leave a strong dark mark, but a light erasable one.
