Wow! I was enthusiastic to get these decals onto the wall, and they didnt disappoint. I am enjoying them immensely. It was my first time installing decals (thanks you tube). Dust off the wall, clean, and allow to dry.  Use a damp sponge and wet the transfer paper surface, then patiently peel it away as you portion your decal.  If the paper drys as you work, continue to moisten. Happy decorating.
