any recommendations?

I have been sewing up some more hourglass blocks (that's the name given to these blocks that are made up of 4 equal triangles), aka quarter square triangle blocks, for my newest rendition of my Hocus Pocus quilt. I wrote about this not long ago and realized after getting a few of the pieces up on my design wall that the dark brown sashing strips that I had planned (and cut a heap of) were too strong for the look I was hoping for. So now I have auditioned some other choices and have moved closer to what I want, and wanted to share the process with you a bit.

Looking through my stash, I found 2 solids that might work. The first one is that first strip that runs from top left to lower right, it is kind of a muddy goldish color up close. When I saw this on the shelf I immediately thought it would be just the ticket, but up on the wall I am not loving it. Then just to the right of that is a brighter yellow strip. When I saw this on the shelf I thought it was way too bright, but when I see it with the blocks I like it. On the right is the dark brown that is getting the axe. And even though I hadn't really considered it at first, there is the option of going with the white that is the design wall showing up between blocks. A viable option, but I am leaning towards the yellow.

I share this with you because I know that picking out colors to put into a quilt is a big road block for many of the people that I meet at the store. They don't feel they have the confidence or the skill to pick anything that goes well together. Well, I have never had an actual art class, never dabbled in paints, never studied color theory. I do own a color wheel, but it is pretty dusty, which shows how often it gets used! Most of what I do is trial-and-error, just like the process I described above. Some of it is intuition, some luck, partly kismet, and mostly practice. What I choose also reflects my personality and mood. How do you choose? If you have any advice, please feel free to share!
