It looks like you're going to have to resend and stain again. You won't have to go down to bare wood. Use different grits from 120 to 300 and clean with tack cloths. Stain in one direction with the grain. Once you have the first coat on, don't touch it again. Once it's dry, then see if you like the results.
It looks like you used a rag to wipe the stain off that wasn't absorbent. Much of the stain is left on the surface. You can wipe off the dried excess on the surface with lacquer thinner and then stain it again. After this length of time it may not be as dark as you need. It may take a darker stain for the second coat. Another option is you have the means of spraying to spray a coat of a dye stain to supplement the color. The dye stain you could use is transtint or Mohawk finishing products makes Ultra Penetrating Stain. It's an alcohol based aniline dye you can even use between the coats of the finish.
That looks like a cabinet I stained a few days ago. My problem was I used a damp cloth to wipe off dust after the final sanding. The moisture in the damp cloth raised the grain and wasn't obvious until I stained it. To correct it, I used my orbital sander and 120 sandpaper. The stain may build up on the sandpaper, so you will need more than one sheet. I finished the sanding with 220 sandpaper and then stained again. Turned out great.
Everyoneís suggestions helped and I am very happy with the result!! Last coat of wood finish is on to protect it! Iíll have to get a picture with better lighting though!. This has been my first project like this. I got this table and chairs second hand and wanted to give them a makeover. Iíve been learning lots and only hope to get better!
