Pillow Design Quandry

First, before I get into the pillow design question, I want to note that I've decided to use my blog as a memory jogger. After spending what seemed like hours this morning searching for a design I recently saw, storing the images here seems the easiest way for me to find things.

So now for the question--I picked up a pillow the other day from the thrift store, solely for the down insert. Both the cover and the insert are in perfect condition, hardly used, but it's a banana color, not so great for most people's decor, definitely not for mine. But it's a Crate and Barrel pillow, not expensive but still not something you'd pick up at the dollar store. So I decided to find a way to foof it up, yellow and all.

This next pillow was on Cluck Cluck Sew's blog and was also featured on Someday Crafts.

I'm thinking the bright yellow Crate and Barrel pillow would look cool with a flower like this. (Tutorial found here.)

Using the same process, different dimensions, she also made this flower brooch. (Tute here.) 

That would look terrific on a bag. And isn't it cool that it's using scraps of fabric? I'm all for using what I already have.

Another design I'm considering for the front of the pillow is this one from Michele Made Me. She calls it Teddy Bear Swim Needle and Hook Book.

Pretty cool, innit? Tute can be found here. Whether or not I use this design for the pillow, I certainly mean to make the needlebook. I do love me some needlebooks!

I don't do that much crochet anymore, but I'm thinking the inside could be adapted to hold tools I'm always misplacing, i.e. my sewing gauge, bodkins, seam rippers. It could be made to be very functional, methinks.

My last idea for the pillow transformation is to translate a rainbow in buttons. How cool is this picture? I'd love to use that as an inspiration but I'm afraid it would take more buttons than even I have.

But a simple arc of buttons in purple, blue, green, yellow, orange and red shouldn't take that many, should it?

So those are my options. I'm leaning toward the flower because 1) I have some pretty cool scraps of fabric and 2) it seems fairly easy. Still, I'd love feedback on which design you think I should choose. All comments appreciated, my friends!
