Matching up fabrics is difficult. I spent a lot of time online searching through fabric.com - I put the word "stripe" into the search box and proceeded to browse through hundreds of striped fabrics.
Last week I was hunting through my attic and found these fabrics. I'm thinking of using the blue fabric for piping and contrast.
My client loves this fabric, so the ballgown version of the KCI Gown will use this berry and gold fabric. Today the fabric supplier confirmed they could match the berry for a contrast fabric for the bodice.
