you will need liquid nail, nail gun, 4x8 1/4 wood panel I bought it for 14 bucks. two work tables really helps with assembly.
Step 2: Cutting panels.
since this door had beveled in lays I cut my outside boards 6 inches by the door length its important make the out side of you door first this will give you the base for the inner panels
Step 3: Cut and glue and nail
since the doors are thin use the panels in place nail gun 3/4 inch are all you need. the outer door edges are solid but inner core is hollow so make sure when nailing you use this to your advantage.
Step 4: Inside panels
each panel need to be sanded to give the edges that beveled look during the look of each board on the inside is it that barn door look also you can make mistakes and just adds a more rustic feel to the door
Step 5: Finishing the door
Finishing the door becomes something of taste I used a homemade chalk paint along with a robe on glaze to finish the door hope you like my very first instructable enjoy your new door for less than 40 bucks I did two doors to be honest
