It is a stylized floral block border and I used a technique I had learned that past year - how to make flying geese the fast way. Over these years, I've found that there are a number of quick ways to make flying geese blocks, all relatively simple, including a 3-Dimensional flying geese. They range from 2 different sized squares (which Eleanor Burns demonstrates in a video) to the square in a square method developed by Jodi Barrows. You can find them all on the internet.
Some of the border blocks up close:
There are two basic blocks in the border.
2: The 2nd block is the floral block; a unit consisting of up to 3 flying geese blocks and a bar if needed. From those flying geese blocks and the bar, I was able to get 8 + different floral looks by varying the placement of 4 colors: pink, darker pink, red, and white. The placement of the green for the leaves was kept standard in all those floral blocks. The only block arrangements I didn't use were #7 and #8.
Just varying the placement of the colors in each flying geese block changed the look of the "flower".
Here's the starting blocks for those pictures. Ones that you can copy, print, and play with colors yourself: They are NOT to correct size though and don't show the seam allowance, but just for you to see how color makes a difference. There are 8 different settings but once you add color, they will seem to make even more. Note that the bottom F.G. block is the same configuration in each, because plants have to have leaves.
