Paint Over the Tissue Paper
Load the roller again and paint over the tissue paper. If you don't like the way the paper lays against the wall, smooth it out with your fingers before painting over it again. Tear off excess paper around the wall edges, corners and baseboards.
Continue in a horizontal line across one wall, overlapping the tissue paper each time so there aren't any flat areas. Cover the rest of the wall in the same fashion, making sure to apply the tissue paper in neat rows.
If desired, take this technique one step further by colorwashing antiquing glaze over the dried surface for an Old World feel.
