How can I make something like a slip cover to cover this couch (pic)?

I'd say, use 2 recliner covers & cover the middle section with a coordinating fabric. If you still use the cup holders, you can cover the middle in sections.

I would sand it, then spray paint with enamel paint. I did this with a chair, came out great. I used 2 coats.

This looks like pleather, and you can make slip covers for it, but I would use an old sheet for practice, after creating a pattern.

Hoe much is your time worth? Maybe you can modify two slip covers for less time and money.

Hi Darcy, have you thought of painting this?

I Would say you will need it have it done custom unfortunatly and that may not be cost effective :(

A few options. I like the last one.

I HAVE USED A QUEEN SIZED SHEET TO COVER MY COUCH. IF THE COUCH IS OF GOOD SIZE YOU MIGHT HAVE TO USE A KING SIZED SHEET. SINCE IT IS TWO RECLINERS YOU MIGHT COULD USE TWO FULL SIZED SHEETS. YOU COULD USE DARK COLORS OR PRINTS.

Ok so i saw that you like brown so click the click. amazon.com/dp/B07KG5G14B/ref=redir_mobile_desktop?_encoding=UTF8&aaxitk=gyNSyU5s7PF85QXk8cZewg&hsa_cr_id=7611697720401&pd_rd_plhdr=t&pd_rd_r=4306db6b-7eeb-46d9-95d5-3c4e3c82c879&pd_rd_w=DB3pc&pd_rd_wg=Fn4e1&ref_=sbx_be_s_sparkle_mcd_asin_0_img

As others have suggested, the best and least expensive way to "fix" your couch is to lightly sand, vacuum, and then paint the surface. There are many Youtube videos available showing info about how to and tips to have the best results.

I just thought of another possible option....You might purchase some upholstery material that coordinates with the base of the couch, use a heavy-duty spray adhesive to apply the damaged area and then lay the upholstery over the adhesive tucking it carefully into the areas beneath the arms. If you measured carefully prior to adhering, you could possibly cut the upholstery to size and hem the edges so there would be no fraying.
