old summer photo for reference

Anyone have recommendations for patchwork cardigans like the style here.. the person i got this from no longer sells this and didn’t offer a style that is thicker and autumn/ winter friendly.. it is 100% cotton.. i know 100% thin cotton won’t keep me super warm but something thicker than this could.. i love expressing myself through my clothes and winter time has been so depressing for me with not having any color.. and starting completely from scratch with my winter clothes.. i’ve found options that are CLOSE but they are all polyester or printed “patch work” and not really patch work.. thank you in advance hope everyone’s staying warm !
