These are a fun and easy project just about anyone can do if you like the rustic pallet look. We took two large pallets and tore them apart. We measured the windows and cut each piece of wood to length and basically rebuilt them into a smaller pallet. If your windows are the right size you can just cut the pallets at the height you would like without tearing them apart or rebuilding them. Once we had the size we wanted we simply lined them with vinyl window screen material, attached them to the house, filled with dirt and planted flowers. They came out awesome, very cute.
