It's no problem at all, friend. Just to clarify, this is the product we use: https://www.amazon.com/Grabber-318111-No-Coat-Ultraflex-Flexible/dp/B07DX4STXF/ not that stuff from the tv infomercials lol. You can bend it in the middle to match the angle of your corner. It comes in a big roll so you can just roll out as much as you need and then just put it on with some mud just like you would with normal tape.

​

If you have any other questions I can help with just feel free to shoot me a pm or something :)
