I decided to gather up some scraps I'd been saving and go at them. They made good gifts during the holidays. The sizes range from the 2-1/2" x 1-1/2" to 3-1/2" x 6". The woods are Red Oak, Aromatic Cedar, Cocobolo, Olive, Holly, Red Mallee and the one in the front right is unknown. Most were finished with home brew and buffed. Some just buffed. All are hollowed through openings from 5/16" through 1/2" hollowed with 1/4" and 5/16" tools. These are fun and fast to make. A great use of scraps. Glue them to waste blocks if necessary and go to work.
