Design and Prepare your Putt Putt Course
Plan your putt putt course on paper before you begin building it. Decide how many holes you'd like to have and how you want them to be laid out.
Mow the lawn for the course. In order to have the golf balls roll better, you'll want to mow your lawn on it's lowest possible setting. This will cut the grass as short as possible. It may require more watering, but it'll help to make the putt putt course more exciting to play on for the kids.
Dig your course's holes. After deciding where the holes will go, give your kids handheld shovels and let them dig the holes. Make the holes more secure by digging them large enough to fit 4-inch flower pots.
Add water and sand trap hazards. Dig several larger holes around the course for water hazards. Dig the ground deep enough to fill with water from your hose. Add a layer of plastic sheeting to prevent weed growth and drainage.
Create other hazards. Use croquet stakes or lawn ornaments to provide other obstacles for the ball to be blocked by or go through. Use some spare plywood and rocks to build a ramp or bridge over the water and sand pits.
Make Flags for the Golf Holes
Saw dowels so they're 15 inches long. Using a dowel with a 1/4-inch diameter will give you a sturdy flag. Make cut enough dowels for each hole.
Cut large triangle shapes out of sturdy craft felt.
Glue the felt to the dowel rod. Place glue on the dowel rod, the length of the triangle. Carefully place the felt onto the dowel and hold it tightly until the glue dries. This should take two to three minutes per dowel rod.
Write or paint the numbers on the fabric. Let your children be creative and make designs on the fabric triangle flags.
Stick the flags in the center of each hole. Place them so they are visible from all directions. When you place the flag in the center, make sure the golf balls can still fall into the hold.
