Hey, all. I've been working with resin for a while now, and decided I was bored of the "standard" molds. So I got adventurous and ordered some from deep-flex (yaley.com). They arrived in about three days (yay!), but I must admit, I am highly disappointed. Instead of lying flat, they either bulge in the center, or the corners are flared upward. All four have air bubbles in the actual mold parts, which leaves a mark on my pieces. I was very happy with the Deep-Flex products I purchased at Hobby Lobby, which is what prompted me to order from their website in the first place. Has anyone else had this problem? Thanks in advance!
