@jjesschan I count corners/sides/ends of squares/rectangles I see. As a bonus, I can't stand to have any number ending in 8 near the top of the object and will start the counter over to avoid this
@Clay_C10 @asmae_toumi That is also what makes it fun. I do everything by hand (no power tools). I'm not very good yet but the feeling of accomplishment when I do complete something is amazing
