I think you also had another post about emb. designs?
I found a card on E-bay that had Steamboat Willie on it. It also had Fantasia Mickey, The Tailor, and a few other historical designs... As stated in my other post I am NOT SURE they are authorized by Disney.. And I would email the sale er of the card to check if the design you want is on the card. They do offer it in all formats.
I have used my machine to make Mickey "heads" using round floral designs in 2 sizes, in the traditional one large and 2 small for the ears...
I know this is not what you want...
Another idea I have done is to paint the design on a shirt/ fabric using fabric markers you can get at a craft store. I take the design and photocopy it in the size I want then tape it to a bright window/light box. I trace the design on the fabric/shirt using either a fabric marker, which is permant or a pencile, or something that will wash out. Then I use Reynolds Freezer Paper that is you can get at
WalMart/grocery store, and iron it to the back of the fabric/shirt. This paper has white paper on one side and a plastic/wax side, which is the side that should go against the wrong side of the fabric/shirt.
Then I use the markers to color in the design. Or I use fabric paint. And then I have used my sewing machine to add free hand embrodiery . If you arn't sure how to do that you can Google it.. .It is thread painting by machine, and you need to drop your feed dogs and just doodle with the machine... using thread to add detail.
Sorry this is so long! Hope this helps you some!
