I have found one answer. Stitch them all onto a large piece(s) of fabric and use 'em as curtains. I used here baby's great-grandparents' linen sheets dyed for a little more color. It would be preferable if you were arty and had a good sense of composition to make your curtains extra attractive rather than let your 8 year old do the layout (ahem).
Even with questionable layout, I'm thrilled with the outcome. It's a fabulous way to bring the faraway French countryside world of baby's great-grandmother into her daily life, and an opening to tell all of the family stories.
