Our LQS just got in Hoffman 3-D Fabric. It's an ocean scene (part of their "Coming At You" line)
They have the glasses and everything. It looks like normal fabric (since sometimes 3-D things look weird without the glasses). Then you put on the glasses and the shapes totally pop out! So cool.
Though I have no idea what I'd make with it. I checked the website's free pattern - didn't love it. It was lots of mitered corners. Any thoughts?
