Spending a lot of time weeding or planting in the garden is a sure recipe for a sore bottom and knees. To cut down on the pain, gardeners often place a kneeler under their knees, or sometimes even sit down on a seat of a special height. Try making one yourself -- or while you're at it, make two, so your little one can learn the ropes of gardening right along with you.
Cut a piece of plywood into a rectangle that is 24 inches wide and 12 inches long, using a hand saw or power saw.
Sand any edges of the plywood that may be rough, and sweep the board to remove excess sawdust.
Cut four 4-by-4-inch posts into 12-inch pieces, or to a height that works for you. If you work in a raised bed that is 18 inches high, for example, cut the posts to 18 inches. If you want to make a kneeler and not a seat, skip this step.
Set the posts on end, then lay the piece of plywood over the top, so that the corners of the posts line up with the corners of the plywood. Use a drill to insert screws through the corners of the plywood and into the posts. Use three screws for each post. If you're not making a seat, again skip this step.
Cut a piece of 2-inch high-density foam, which you can find at a craft store, into a 24-inch-by-12-inch piece.
Place craft glue or spray adhesive onto the top side of the plywood piece, then stick the foam to the board. Allow the glue to dry.
Lay a 30-by-18 inch piece of vinyl or upholstery fabric over the top of the foam, then wrap the fabric around to the back of the board. Using a staple gun, insert staples every 1 inch around the perimeter of the board.
Trim off any excess fabric from the back of the board.
