The one I made for a birthday last weekend went really fast (had to...started it on Thursday evening for Saturday birthday).
I did 4-1/2" strips of various butterfly fabrics alternating with 2-1/2" strips of lime green. Stitched the strips into a tube and cut 4-1/2" strips off the tube which I then alternated with 2-1/2" lime green strips.
This worked out to be 5 squares by 9 squares. By adding a 1" border then a 3" border it ended up being approximately 45x60.
I tied little narrow darker purple ribbon bows at each intersection.

You could easily make this whatever size you want by adding more and/or wider strips.
