Wow Carol, those colours are breathtakingly beautiful and your centre star looks fabulous, can't wail to see more of it. I used dupion silk to make my twin grandchildren christening gowns, my daughter wanted an all in one suit for the little boy in a blue I chose ice blue and she wanted them both smocked and let me choose the colours and style etc, The little girls was in white, or almost white with smocking etc. I also did little hats and I made some shoes on the embroidery machine, it actually made the fabric for them as I used thread to make them they were the exact same colours as the gowns, The silk did tend to fray and so I stabilized the edges and they were fine especially as I was smocking them, it gives the fabric time to fray,but they were fine, they turned out absolutely beautiful, I have always loved silk and everytime it comes on a good special I just have to get some so I do have some lovely colours.
Can't wait to see more of your quilt, it is just going to shine, silk has a life all of it's own.
