So, we have this old couch. She's been with me for 12 years.
She presently resides in our living room so it doesn't look bare.
I got an idea from somewhere, if it was you let me know so I can credit you.
A slipcover made out of drop cloths from HD.
I tried it. Half is done. Check it out

PS I keep jamming and breaking the needles on my sewing machine (I need a lesson) so this was made with fusible/hemming tape with an iron.
