I call these wine pour holders.  2 1/2" square for the small one, 2 1/2 high about 7-8" long.  The top and bottom is press fit with a little glue.  The stem on the wine pour is less than 1/8" in dia.  I just drill a hole 1/8" in the center.  I use a miter sled to wrap the grain.  WOP finish.  I made about 1 dz of the small ones and finish them off If i need a gift.  BB1 there is real cool material in my cut off bins!
