Cedar Hollow Form: 11-1/4” x 7-1/4”. This is my seventh hollow form and first end grain. I’m getting more comfortable with the system now. It is 1/8-3/16” thick which worried me due to cedar being so brittle so I had to use a gentle touch. It is very light so may need to add something inside to keep it on the table. Next cedar one will be a little thicker.
