I made several of these and I like how they turned out. I tend to go monochromatic when I first start with a new style, but they do have their appeal to me. I started with a smaller bracelet blank and used smaller sets of buttons for this one. It's been my experience that when people sell vintage buttons, they don't really sort sizes much. It's usually by color. The result is a variety of sizes to work with. In the 600+ lot that I bought off of Ebay, there were a bunch that are too big for me to work into the two sizes bracelet blanks I'm currently using.
I've seen people string large buttons together as a platform for smaller ones, and might try that at some point. Another idea I had is to use the larger ones to make brooches, mixing clay tiles and buttons again. I like the variation in color and texture. It's interesting to me that the process of putting the elements together isn't easily rushed. I have to sit down with a bunch of buttons and tiles in front of me and try different things until I get combinations I like. There's an orange one I love and I'll post that one soon.
