THis issue comes up about twice a year...how to attach a pattern.
There are a number of proper ways and twice as many 'I have a problem way.'
1) Use painters tape on the wood first, attach the pattern to the painters tape
with spray glue then top it with clear packing tape.
2) My preference is ...Use 'GLAD Press N' Seal attach pattern with spray glue,
top with clear tape.
3) Just spray the pattern with spray glue, cover with clear tape.
Use lacquer thinner to remove the pattern.
There are other methods, these are the ones I use without any problems.
