Step 4: Arms and Back
When adding the arms and the back, it's a good idea to reinforce with some green choice exterior block adhesive to secure to the base and prevent any shifting of the blocks when people sit and lean back. Place arms first...2 Full/Finished Blocks. Three Full/Raw blocks will then be positioned as the first row of your back. Top off back with 2 Full/Raw blocks and 2 Full/Finished (placed on each end).
