Portrait images are made using your choice of photo. I hand trace it for the best quality image, then convert the image and create a stencil. Engraving is done by sandblasting and the result is a much bolder and more even etch than traditional etching cream or laser engraving. Please include with your order the photo that you would like used to create the design. Feel free to contact me with any questions. Once I receive your order I will create a mock up of the design for your approval. Once you have approved the design I will engrave your glass and send you a photo of the finished work before shipping.
