I put a layer of painters tape on the wood then use a glue stick to stick the pattern to the tape and a layer if clear packing tape over everything. I use a glue stick because I don't like having to go out in the cold to use spray glue, it is too smelly to do in the house.
I like this method because taking it off is fairly easy no matter how long I have been working on the project. I get sidetracked and sometimes it takes months to get back to a project.
I don't like mineral spirits, I am really sensitive to the stuff (one drop burns on my skin) so I usually just pick and peal the tape off. Sometimes I will use my hair dryer to heat it up a bit.
There are lots of ways to get the pattern on the wood. None of them are wrong, find one you like an go with it. If you feel like trying another method, go for it. The important thing is that you are happy with the process/results and that you have fun while scrolling.
