Our couch is D's from roughly forever ago. It is beyond faded, and since it's been very well loved, the material is starting to rip in places. Given that once upon a time it was a denim blue colour, I thought it might work to patch it with various denim scraps. In the process of patching one large rip today, I made a secondary rip - oops - hense the over lapping patches.
I think that one day, the entire couch cushion covers may be a big patch job.
It'll look even more loved then !!
