The colors of the Blossoms Sewing Kit were accidental.
If I were going to stitch it again I would not use the white ground fabric. I would use a darker antique linen that was almost brown. That way both the white stitching and the pink would show up better. The two blossom bands would also be the same (not be the reverse of each other).
But, it's really, really pink. Way too pink for my tastes so I would probably use other colors. I don't have the time to stitch it over, but I have the next best thing ... software.
My first alternative color scheme is the colors of the sunflower. A dark bright yellow and oranges and browns for the center.
The next color scheme is a forget-me-not. Blue petals with a yellow and white center.
And finally, a darker red with the same yellow and white center that resemble no flower that I can think of.
Once I got started changing colors I wanted to keep going - there are so many possibilities. But my favorite is the the first so I'll stop here.
If I have time I'd make a Sunflower Sewing Kit.
