Thanks for the video link. I had seen that before but forgot about it. My pendant trays seem like they are 3 times that deep. I'm not impressed with the amount of resin it takes to fill them.
I will try working in two layers. Has anyone done that before? I switched to mod podge for sealing my image, and I think the air bubbles that I'm getting are sitting in the brush strokes from the mod podge. It's been quite a bummer to not get a perfect image, especially b/c I thought these were going to be such good sellers for me.
