I have some mineral spirits, so I'll use that to clean off the table. Probably need to wait until tomorrow at this point to do any more coats. On and off, I've been regretting using the wipe-on stuff. Would there be any issue switching at this point to a brush on. I know the dry time between coats is longer, but I like the idea of it going on thicker. I'll also pick up some mineral oil tomorrow and use that in the wet sanding from now on.
As far as the knot hole... the table is for my wife. It's actually just a re-finish of an old table that my wife wants to use for a sewing table. I made my own wood filler from the initial saw dust to fill in the ends of the top where the laminations had separated (the table actually sat unfinished outside for an entire Oregon spring with lots of rain before I started this project). She liked the knots however... they do look kind of nice in a rustic way along with some small checking on another part of the top.
