This is the best sewing transfer paper I have found. Apparently others agree and it is all sold, but more is arriving around the last week of April.
2 large sheets (11" x 17") of Olympus brand sewing carbon for transferring sashiko designs to your fabric. You lay a sheet of this transfer paper face down over the right side of your fabric. Cover it with your design, right side up, and trace the design with a dull ended tool ( I use a ball point pen, but if you don't want to 'muck up' your pattern buy a Hera marker to use) Check that you are putting enough pressure on the tracing to transfer a thin line to your fabric) Rub gently with a damp cloth, or wash, to remove. Sheets are reusable many times. Please not on some occasions I may need to fold these once for shipping. It won't damage their use.
Color: Comes in either White or Blue. The blue shows nicely on very dark navy fabrics, but not on light to mid blue fabrics. Of the carbons I have used I think this one makes clearest and best lasting lines.
