Hey, thank you everyone who took the time to write me with various solutions/fixes to the problems I've been having: I'm now overwhelmed with solutions instead of with problems, which is progress ...
This is my first attempt at a solution.
Normally I post directly to Blogger from Picasa--that is the only way I post, in fact: it's easy--I upload and edit my photos there.
These photos are from the photos file on my computer, which, in all honesty, I hardly ever look at--I don't know how to edit the photos there, and they're stored all haphazardly (or perhaps I should say I have stored them all haphazardly ...)
So here they are, unedited, my first two tries, both unfinished, at a deceptively difficult challenge at Daily Paintworks: paint a white object on a patterned cloth.
