Novice needs a bit of help - joining + stain
First post here. First piece of furniture I am building (though that will become obvious as you read on). My wife found a dining table she liked and instructions online, so I got busy. Without ripping/jointing the edges of the 2x10x8's (I know, lesson learned), I glued and clamped them together, then put cross pieces underneath with dowels and glue through to hold them together. I cleaned/sanded off all of the squeeze out. They actually fit together decently. It is supposed to be "rustic" anyways so a little imperfection is OK.
Here is the problem:
Because the lumber comes with rounded edges, there are little grooves between the boards. This is fine, but there is also a little line of glue that I was unable to get with the sander. I haven't stained yet, but when I do, I'm guessing I will have yellow lines down the middle of my dark brown table top.
What can I do? The wood is white pine. If I fill the grooves with stainable wood filler, it would still be noticeable, right? I'm basically nearing the end of my free time, so I'm not too interested in cutting it apart and starting over.
I greatly appreciate any advice you could offer.
Thanks for reading this short novel!
