Slip cover for sofa or loveseat (Chapel Hill)

Hi ! Got my new kitten and she got caught in my new sofabed. Yikes. So I cut open the back of my sofa at 1 am and Saved her!!! Looking for a slipcover and I will sew a bedsheet to it on the bottom to encase the Loveseat sofa completely. I’m joyfully exhausted!!! Ha ha !
