Doug's Tip

Always allow an extra 10% for waste when planning materials. It saves you a second trip to the store and ensures you have the best pieces for the most visible areas. This small buffer gives you flexibility to prioritize quality, correct mistakes, and make sure your finished project looks polished and professional.”
