Lovely quilts! Overall paterns woult work great. The quilts are wonerfully visual so no complicated quilting is needed. Let the quilt speak, not the quilting. For your sister I would do something with swirls to mimic the wind in the pinwheels.The bear paw is beautiful and anything simple would work.I like circles in circles on the leftover quilt, very nice.The broken dishes would be nice with something curvy to soften the angular points. They are all great!
