These arts and crafts tables are made with 3styles of mortise and tenons. Each table is built with 4 through tenons, 4 tusk tenons and 12 traditional mortise and tenons. 20 mortise and tenons each will really improve your skills. (However I cheated and used my dedicated mortiser). No nails or screws were used, instead I used ebony for the plugs to hold the through tenons in place. I used my recipe for the stain to match some antique arts and crafts furniture I already have.
