I have placemats in red, white, orange & blue. My napkins in red, blue & white. My tablecloths are white lace (3) & one solid green check. I have quite a few candleholders, & maintain a supply of candles in red, green, white & blue.
I also have some small seasonal decorations that fit on my bookshelves in front of the books - pumpkin & pilgrims for Thanksgiving, an apple for the patriotic holiday, lamb for Easter, nativities for Christmas, etc.
