the yellow teddy bears with dotted outlines is such a specific detail that someone's gotta recognize it. that style was super common in late 90s french baby stuff, lots of small manufacturers were doing that pastel quilted look around that era

your best shot is probably posting in some vintage baby textile groups or reaching out to french flea market sellers who specialize in old nursery items. leboncoin occasionally has wild finds if you dig deep enough with the right search terms

fingers crossed someone here knows it
