Our four dining room chairs are done (2 more to come soon) so I thought I'd give some insight into the process.
Step 1: acquire your clean, unfinished furniture, fresh from the store
Step 2: (not shown) disassemble, making sure to number each chair and seat so they fit together afterward
Step 3: apply primer to avoid nicks to heavily used furniture
Step 4: make a huge mess out of your living/dining rooms while everything is stained and painted
Step 5: re-assemble and enjoy the view
Step 6: sit and eat!
Step 7: buy two more chairs and repeat steps 1-6
