Pretty quilt. I also "inherited" (inadvertently) similar butterfly "blocks" only, not put together into a top yet. There were 3 tops and several sets blocks only from my dad's mother (so I am told) in my mother's house. I did finish the "prettiest" top on the machine in 2019, which had yellow flowers applique'd on muslin and green lattice. I used yellow binding. I do like the pale pink & green color scheme on your butterflies for inspiration. I need to lay mine out to see what size they might become and what colors might work. Thanks!
