You want to go ahead get rid of any score marks that may be there. See if all the lines are right. It's looking good. Now when the strings are attached to here it will hang. But we're missing one thing. Boop. You don't want the roots to rot. Remember when you make planters don't ever bring them up to stoneware temperatures because if your clay has become completely vitrified it won't breath. So that means if the clay is not breathing the roots in your plants aren't breathing which means you'll get root rot which means your plant will die because your pot killed it. And that's not nice. You get a little drainage hole there and another drainage hole. Okay? Now we have a hanging planter. It should be fired maybe like a racu or you can fume fire it but don't bring it up to co and 10."
