I love the skirted table that Erika had made for her daughter's second birthday. The fabric is very inexpensive, and she chose red so that she could use it again on holidays (how festive will it be on the 4th of July?).
Our dining room table's surface takes a beating when we have guests and it would be nice to have a floor-length cloth to use when we pull the chairs away. Ana Spiro has a lovely ticking-stripe cloth on her desk.
A box pleat would be pretty, too, and that might be a little more in-line with my sewing abilities. Now, where's my measuring tape?
