DIY Image Transfer onto Leather
Use Citrasolv (a natural cleaner) to easily transfer images onto leather.
You need to use a laser printed image, or a zerox/toner copy. Ink jet printed images will not work with the Citrasolv method.
Another option for transferring images to leather, is to use tee shirt transfer paper. Lana Red uses iron-on tee shirt transfer paper to transform leather scraps into jewelry here.
