I have been sitting in my Sencha pattern for awhile. I love the vintage look, but have not found the right material yet. I bought a couple of yards of $1.95 pink cotton with small white dots on fabric.com to trigger the free shipping, and when I got it out of the box it spoke to me. The fabric said, "Make me Sencha version 2." I washed it. I dried it. I laid it all out and found greasy looking stains. I washed and dried it again, and they didn't come out.
I circled the marks with some disappearing marker.
I loved the look so much and bought matching buttons, so I ordered a couple more yards of the fabric which I will totally inspect before washing and drying. I did decide to make a muslin out of the icky stuff though just to get an idea for the fit. Obviously it is not done much beyond the darts, shoulders and half a side seam, but I'm loving it!
