I had to put at least one block together from the Bonnie Hunter mystery quilt . . . just to see. And I'm not convinced that I like my choice of brighter yellows. I'm actually glad that I haven't cut any more of the yellow units yet because I need to live with this block for awhile before I decide how to proceed. So my pieces and parts are all pulled together and set aside where they can't get lost.
I've noticed on her Quiltville Open Studio Facebook group that some folks have replaced the yellow squares with yellow and neutral HSTs. And others have replaced them with purple and neutral HST. But most have been posting photos of gorgeous quilts with the yellow as is. So I just need to let this one rest a bit while I play with some options.
