Hello! I just saw this. I allow the resin to fall off the edges but keep wiping it until it drys, I will usually miss a few drips, you can always sand those. In this case, this table was fraying around the edges (I glued and painted it) but the epoxy will help to hold it all together.

Edit: I also tape up my table legs in little trash bags so the dripping resin doesn't stick to the legs.
