This is a set of three maple hollow forms. The walls and base are 1/4" or thinner, but the tops are tappered as I don't have my "hook" hollower done yet. The largest is 6" tall and 6" at its widest point and the smaller ones are both about 4.5" tall and wide. Finish is Watco danish oil, I think I will buff them out to get a little better shine on them. By far my best finish to date though. Comments and critiques are encouraged.
