I am working on more of the wild variety, but have also started a silver gray color scheme, and a naturalistic yellows/browns theme to mimic sunflowers.
An important follow up I am going to add to the tutorial is the 'learned the difficult way' information regarding the background. Choose your background colors and size, piece, quilt and bind it, THEN place your flowers, stems and leaves onto it. I used masking tape to hold all the fluff and stuff aside while I struggled to quilt, which made it doable, but still difficult!
I will post a picture soon of the sunflower or gray theme, as I have come up with a further embellishment-little flower as center of big flower. Way cool!
