Never say never, there's always a possibility. I remember thinking stuff like that in my life, that'll never happen, and then...it did. I guess I work on the premise that I'll gravitate towards the things I think about most, (do the things required to attain them because I am so focused on them.)
But if you never eat frogs legs and snails you're not missing out on much. Lol.
I used to use a sheet strung up on the wall and have used a curved piece of thin coloured card-stock paper sticky-taped to the wall too. (The curve removes the shadow that angled corners make). I'm happy to try a few things, play around a little, as it adds to the enjoyment. I have a plan for the lightbox and when it happens I'll do a post I guess.
