Dear Creative Artists,
What a wonderful time painting with you Saturday.
Here are a few links I promised you:
Here are some aurora reference images for inspiration.
Here are some images of my alcohol ink paintings of Northern Lights.
Here is a link on how to seal tiles. For Yupo paintings I just frame under glass and away from direct sunlight. I do not seal my Yupo paintings. Some artists would put a few light coats of Kylon Kamar varnish on and perhaps a UV Spray.
