I found a fallen cherry tree in the woods, it is airborne, and dried. the bark has decayed, and I decided to try a NE bowl from a root. Do you think I should fill the indent area, and other cracks, before I finish sanding? The decayed bark comes out very dark with oil. This is my first NE. The missing piece of bark is under my finger nail I would like to have your comments on finishing this.IMG_1145 (Large).jpgIMG_1143 (Large).jpg
