Sand your pallets so that they are smooth and free of rough edges. The Ashley Ann Photography website (see Reference) suggests using 80 grit sandpaper first and then follow with a 200 grit sandpaper to smooth the surface of the pallets.
Bolt the two pallets together. Be sure to bolt both the top and bottom edges of the pallets. This provides extra security and sturdiness.
Paint your pallet daybed. Choose a color that fits your style. You may choose a paint color that blends in with your room or you may want it to "pop". For example, if there is white bead board in the room where the pallet day bed will be located, paint the daybed white to blend in.
Add wheels. Using a hand held drill, screw on caster wheels to each of the four corners of your pallet daybed.
Purchase a thick foam mattress for the top of the pallet daybed. Be sure to measure the size of mattress needed before purchasing. A mattress or fabric store will carry this.
