Jacquard Cotton Sateen from Dharma Trading Company online, and took it to be printed at Museum Quality Framing in nearby Camarillo. The owner has a large Epson printer, which uses archival inks. The Jacquard cotton is pre-treated to make it inkjet-ready. I gave the owner a print of the image so he could ensure that the colors were true to my image.
The paper backing on the fabric must be removed carefully to avoid distortion. Since the entire piece, image plus margins, is 42" wide, I asked a friend to help me remove the backing. The best way to do this is to peel the fabric back all the way across the edge (about 2"), and then hold that edge down, while the other person pulls on the paper and removes it. Since you are not pulling on the fabric per se, there is little or no distortion.
I then backed the cotton sateen with a fusible featherweight Pellon stabilizer, shown in the photo above. I purchased a queen sized wool batting -- read: wrinkly when unpackaged, but a dream to quilt. After I cut the appropriate size (including extra), I put it in the dryer on air fluff to try to get out the wrinkles. Nothing. I added a slightly moistened hand towel, and voila, wrinkles begone! This does shrink the wool batting, so be sure to allow for that when calculating its size.
I spray-basted the digital image-top to the batting - always spray the batting, not the fabric. As I do not want the stitches to show on the backing, I will attach that later. Now I am using all those luscious threads pictured with Sanjagirl in my February 1 post and am spending delightful hours in the act of stitching.
