Hello Gay - I think your fabrics are lovely and I immediately thought of a recent email received from Rachel Hauser of Stitched in Color. She's preparing for a sew-along soon with her recently released Honeycomb Stars pattern. I realize this is not vintage/antique but it would be a beautiful quilt made with your fabrics. Here's a link to her site -

Another thought, Jen Kingwell's soon to be released book - Quilt Recipes - has several patterns that I think would finish lovely in your soft, pastel colors. Wensleydale and Diamond Exchange are my two favorites. Here's a link -

Just my random thoughts - look forward to what you decide and hope you find your mojo soon!
Hugs, Christine
