Dave found 1600-foot rolls of 1mm reed at Amazon for $12 -- much less expensive than I thought they'd be -- so I asked him to place an order for me and they'll be here in my hot lil' sewing paws before the week is up. I'm hoping for Wednesday.
While I wait for the reeds to arrive, I've been working on the straps. I figure that I can stitch them on before slipping the reeds into the body, and then when I put the chamois binding on, it'll be solid enough, and hopefully not look too odd. I'll post pics of the attachment when I do it, so you can see what I came up with.
The back strap piece looked a little bland all by its lonesome, though, so I got creative and decided to add a little touch of fancy by quilting in a few flowers. My blue washable fabric marker makes the design easy to see, but the actual stitching is in pale pink; subtle, girly, and sweet. Three things I'm not, but doggone it, if you can't make secret pretties for yourself, who can you make them for? At least they're not angel wings. *smirk*
