I love the little bits of metallic that I included in the quilt - she's got touches of it throughout the nursery so I wanted to have some in the quilt too. And I added some rick rack for color & texture.
Wasn't sure of what fabric to use for the metallic, so I ended up buying a bit of gold lame and then ironed on some fusible interfacing to the back of it. I stitched up a little sample block and quilted it - then threw it in the wash a few times and it seems to be holding up just fine in spite of the fact that the fabric bolt said to dry clean it only.
We found that the best way for choosing the various colors was to pull paint chips from the hardware store - I carried them with me from quilt shop to quilt shop searching for the best match - worked great!
She found the inspiration for the quilt on Pinterest (of course), a rug that is no longer available (photo below) - worked great for a quilt too, don't you think?
I can't wait till the entire room is put together and I can give you a tour. Two months till her due date so we're both making good progress.
