Experimenting with a quilt pattern

I have made numerous quilts before now but I usually start with a pattern then tweak it to fit what I like.   A friend sent me a small picture of the corner of a quilt she liked and asked if I could figure out how to make it.  I studied the photo and came up with a simple crude pattern. Excuse the scribble look to this but this is the pattern I drew out.

Once I drew it out I figured out how many half square triangles I needed.  I used 4 inches to get a quilt that turned out to be about 50-60 inches square once it was made.   I had this fabric in my stash just waiting for the right project.  I bought some of every color of these roses. I also had just enough of the white on white roses to use as background fabric.

I used green in place of the orange in my pattern and this is what I came up with.

I hope to quilt it next week....I will post a finished quilt picture once I finish it.
