Last month while working on a collage background for a Hawaiian style paper cutout of Palm Trees, it wasn't turning out the way I had envisioned it in my mind. Does that ever happen to you? You have a picture perfect idea in your head and it doesn't come out the way you planned. That happens to me frequently enough that now I'm no longer surprised, and that's okay. There was a time when something didn't turn out the way I planned and it would frustrate me to no end, but I've learned to keeping trying. "If at first you don't succeed, then try, try, try again". Who said that?! W.C. Fields, that's who. He also added another colorful line to that but I'll leave that up to you to Google <wink>.
After the initial TRY I began to rework the background adding a bit of yellow ocher paint and it was soon clear that wasn't working, it was overpowering the palm tree design. So I quit at that point, disappointed but knowing I'd come back to it sooner or later to TRY AGAIN.
Trying again at this point is what some would call salvaging ....stripping off some of the background papers and using sandpaper on the rough edges of the remaining paper on the canvas I was able to add a layer of light back into the background, with just a touch of ocher.
Blending in the lighter colors with ocher seemed to give the right effect and no additional paper was needed to complete the background. Gluing down the palm tree design was the final step and letting the whole canvas dry for several days before declaring it DONE.
Don't give up on your collage or painting when things aren't working out as planned, just walk away and let it go. Then come back later and try it again. There is always an "ugly" stage when I want to trash my work but I've learned to work through this by pushing through the ugly to the final stage of beauty. Sometimes the best laid plans don't work out the first time and that's when you must TRY, TRY, and TRY AGAIN.
Keep ON Trying and Happy Painting!
