I really needed this item quickly for a round altar linen for church/hospital chapel. It did not arrive as quickly as I thought it would (maybe I'm spoiled by the speed of delivery from Amazon). When I received the item, it was entirely rolled up and it wasn't until I attempted to use it that I noticed the jagged edge down more than half of one side of the ruler. I notified the shop, they did offer to send another one, but I declined as I need this item for the church project. I let the shop owner know this and that I would have to put tape down the entire side so it didn't snag the linen material and hope that I could finish the project on time. The owner said that was a good idea. I decided to not put the tape on the ruler, but used an emory board to try to smooth it down. It was an expensive item, in my opinion, and I would probably not buy this again. It was impossible to smooth it completely. I hope all the items like this do not have the same jagged plastic edges.
