The "boot" napkin holders are simply cut from an embossed faux leather and sewn together only on the sides (left open at top and bottom).
I made a simple rope "loop" to slip over the glass.
The dining room is set up a little more formally. The round table in there is 75" across, so I can seat 8 people easily. I found these sweet little salad/dessert plates at Walgreens for $1 each! I already had white plates and red chargers. I made simple little napkin holders of loops of stretchy sequined ribbon ($2.50 for a roll).
The centerpiece is a wreath surrounded by a garland of red berries. I placed a plant stand in the center, scrunched the leftover ribbon around the space between the wreath and the stand, and placed a frosted red-polka dotted trifle bowl on the stand. The poinsettia was set in the bowl. I placed a dove on the side of the wreath. There is a cardinal on the other side.
The pictures don't show the complete table settings since I still have more napkins to make, but I think you can get the general idea. We will eat "buffet" style since we have to sit at two tables, so I didn't need a lot of room on the table for food. I also didn't put out place cards because I want my family members to sit at the table they like best.
I still have a lot of time to make little changes and improvements to my tables, but I can enjoy the decorating during the entire holiday season!
