General Inspection

Eliminate any wrinkles you find in the covering by shrinking
them away with a low temperature setting on a heat gun, then
apply pressure to the area with a covering iron and a hot
sock. This will securely bond the covering to the wood so the
wrinkles will be less likely to reappear in the future.
