From Good Housekeeping: several mini white pumpkins on a tray!
Gather up all your glass vases and containers, place candles inside and layer in hazelnuts, walnuts, or pecans.
From Martha Stewart: Pear Place Cards. A twist from me~ instead of place cards, place pears on a pretty tray (or by themselves) in a long row down the middle of the table and on each card write down one thing you are thankful for this Thanksgiving.
From RealSimple: Place pinecones in different sized glass bowls and vases- wrap ribbons around the containers if you want to add an additional touch.
Fill a large glass vase or pitcher with candy, nuts or fruit for a fast pretty centerpiece. For Thanksgiving, try candy in fall colors, like mini Reese's Pieces or M&M's. This will work great as a Christmas decoration when filled with Hershey's Kisses or Red and Green M&M's!
When guests are on the way and you have empty space to fill on the table, try this idea from RealSimple!
