Adria, You understand you will never get the filler the same colour as the wood (different material). your best bet is to find a courner ( that no one will see ) and try to get a good balance with the filler/wood. always use a filler a "little" darker than the wood, so when you stain the wood (which is always a little darker, you may get a good balance. Fill the cracks before you sand, this way you will not have lumps of filler, use a fine sand paper and go with the grain of the wood, same when you stain the wood go up and down with grain. if you cant get a good balance with the wood/filler, put carpet down. Best of luck. John 2000.
