This table is in my entryway and it was the first one I tried making. I laid a piece of felt over the table and put in pins along the top edge so I wouldn't cut the drips up too far. I turned it onto the backside once the pins were in and drew the drips with a sharpie. Just cut along the lines and you're done!
This is the hutch in my dining room. Same basic steps as the other cover, but I didn't have to do any corners on this one because the sides fit along the inside of the opening.
