I absolutely LOVE applique borders even though they are a pain to design and sew. Here is my probably over cumbersome way of doing it just in case you want to design your own some day.
First off, I make copies of all the things I think I might want and cut out a full size piece of graph paper (any paper will do but I'm kinda addicted to graph paper).
Then I doodle and make notes and get a good first pass. I found at this point it's important to start making applique shapes so I can see how it looks with actual fabric.
Once I get about of 1/4 of the pieces on I baste it and have a look. The thing I noticed here is that I think it needs some of the light blue and since ladybugs solved my color problem last time I decided to try butterflies this time...I'm sensing a bug theme here.
Here I have jazzed up the corner with a bow and added some butterflies.
Now that this is all together I photograph it again and so some Photoshop gymnastics to see how it's all playing together...so far so good. I'm not terrible thrilled with the white space in the middle of those edges but I have enough to get started...this has me thinking about what to add there too.
