Also check out the $$ stores for the kitchen cutting mats. I found them in a 3-pack for $1.29, put your pattern under and then draw with permanent pen. They can be cut with utility scissors into any shape needed. They are not heat proof and not for rotary cutters. You can put down the mat pattern and use your ruler and cutter to follow the straight line pieces.
Have bought a number of them just for my quilting and for purse patterns I make often.
