Found a trio of batik fat quarters...just enough to cut the sashing at 1.5" finished (2" cut). Here is the grid layout (yes, I didn't make the bed this morning).
These butterflies are hand appliqued with turned under edges. The antennae are embroidered using Stem Stitch in black. I like the pattern so very much, thinking about doing a fusible version wall-hanging for myself (or maybe a grand-daugther?) as well when this quilt is done.
