Have you ever done a looped pile carpet repair cutting a diagonal instead of row cutting? Some people re oriented their wood stove hearth, so now its parallel with the walls. A 5' by 5' repair piece needs to be seamed on in this corner. The carpet is 25 years old, and white and in good shape. Loops are medium height, not like a fat Berber. They have a large piece of carpet for the repair. If I do the seams on rows, it will put the repair way out in front of the hearth. A diagonal seam wouldn't be nearly as far out in front of the hearth, and would end against the wall where furniture will set. Being the carpet is old and has faded, the seam will show regardless. It's an olefin product, so out from the hearth it has flattened from being walked on.......... row cutting for a head seam will be difficult if it's even possible.... I doubt it. If I do a diagonal cut, the carpet is not flattened where I'd cut the seam, so the repair piece will match the pile thickness and texture of the existing carpet. I'd of course have to very carefully cut and seal the loops and probably end up trimming the top a bit once the seam is done. The carpet has faded, so it's not gonna match anyway........... Should I break the rules?
