THANK YOU FOR VISITING MY CHANNEL. DON'T FORGET TO PRESS THE LIKE AND SUBSCRIBE BUTTON. TO MAKE STAIRS EASY, FAST AND PRACTICAL, WE MUST ADJUST THE SIZE OF THE STEPS WITH THE SLOPE OF THE PARENT LADDER, SO THAAT THE SIZE OF THE STAIRS BECOMES IDEAL. NOT YOO HIGH AND NOT TOO WIDE. SO IT IS NOT DIFFICULT OR DOES NOT FEEL TIRED TO RIDE IT. AFTER ESTIMATING THE SIZE OF THE STEPS, THEN WE PULL THE THREAD ON THE SIDE OF THE WALL WITH THE SIZE THAT WE HAVE THE SIZE THAT WE HAVE ADJUST EARLIER, SO THAT THE SIZE OF THESE STAIRS TO BE ALL. THEN WE MADE A MALL TO INSTALL AND STRAIGHTEN THE STONE PAIRS. SO THAT OUR WORK BECOMES EASY AND FAST. NO NEED TO BOTHER STRAIGHTENING THE PAIR OF STONES WITH THREAD. AND TO FLATTEN IT ENOUGH BY USING A WATER PASS. FOR SIMPLICITY, WATCH THIS VIDEO CAREFULLY.
