Hello and thank you for your honest review. We try to make these products to fit universal needs, which also means that occasionally someone may have to trim a piece of moulding to fit their specific needs. We opted to make the moulding the same size as the coordinating sheets of lattice, knowing they could easily be cut down using a saw to fit specific needs. After reading your review it appears that you did everything correctly and we hope you weren’t too inconvenienced.
