I love Gravity Falls, I've seen it a billion times (no seriously,  I watch it on repeat I'm weird like that) and I've done a lot of stuff from Gravity Falls for my Redbubble shop. I figured I'd put a few of them up cause some of them took a lot of time to to do and they came out pretty cool. The first one of Mabel in the hamster ball, the ball is actually transparent, but it doesn't really show, especially on the stickers because they put a white background behind them, you can see it a little on some of the t-shirts though.
