In order to be able to make small details I used Swedish Tracing paper.
Swedish Tracing paper is normally used for- you guessed it- tracing patterns. It is a kind of non-woven and you can sew right through it without dulling your needle.
Step 1: How to prepare your print
Print onto regular printer paper to check the size.
Cut at piece of Swedish tracing paper roughly the size or your printer paper. Attach to printer paper using double sided tape. (Not regular tape as that is going to melt and ruin your printer).
Print again. I chose to print my tracing paper upside down since the original top side was slightly wrinkeled.
