Summarize this article:

The oil needs to dry completely before you can use your tracing paper. This may take up to 24 hours, but if you don’t want to wait as long you can use a hair dryer to speed up the drying process.  Once the paper dries completely, your tracing paper will be ready to use! Sunlight will help the paper dry more quickly, so put your tracing paper by a window.

Summary:
Allow your paper to dry overnight.
