Thanks ladies! I think it will be impossible to match if I order online, so I will be limited to what I can find in a brick and mortar. My local quilt shop stocks the entire range of free sprout solids, so I know I might find something there. The shop in fabric row did not have a suitable lining fabric, and I don’t remember seeing something at the other shops either, but I could try again. Otherwise, maybe a contrast lining. Maybe a soft yellow batiste? Just thinking aloud. I’m not a blue person, but this shade is extraordinary.
