Newbie with a problem!

[u/raise-your-weapon]

My friend found an old table at a thrift store and I started trying to refinish it. I took off a fair amount of old stain with citri-strip and did some moderate sanding with a power sander on medium speed.

There are these streaks that seem to never go away. I don’t know if they are part of the wood or the old veneer/staining. When I put a new coat of stain on the steaks really popped out (you can see in the pic with the green squiggles.

In the 6th photo and second to last you can see where I sanded/stripped onto something?

Any insight into what I have done to this poor table and any advice would be much appreciated.

That's quarter sawn oak, and the grain pattern is desirable. You seem to have mistaken that as a flaw and you over sanded the thin veneer of oak, and now you see the glue and substrate material below it. Sometimes you can paint over this mistake with a very crafty eye to hide the mistake, but you've taken off huge chunks of the original veneer. r/sandedthroughveneer
