Your image on glass in your choice of colors. Please email me first through the Custom Work contact page at the top, and tell me about your idea or image, and any color preferences you have. I will email you back and answer your questions, and you can then send me your photo or artwork. Image should be a larger file, around 3x3 and 300 dpi, ideally high-contrast, (but I can do this in Photoshop) and not copyrighted by anyone other than you. I will email you a mock-up with your image/color ideas and ordering instructions. Once a design is worked out and agreed upon, you can go ahead and order it here, noting the design + colors in the comments field (ie "bird platter, brown on ivory, red border"). I can get started as soon as I've received payment. Custom work typically takes about 2-4 weeks after the order is placed, and is not returnable.
Cufflinks are printed in one color with fine enamels onto colorful sheet glass, then fused it in a kiln to about 1400 degrees. After fusing, they are cut to size on a wet saw, shaped with a grinder, then returned to the kiln to fire polish the edges. They are screen printed, kiln formed glass, and about 5/8" square. Silver plated cufflink t-backs are glued to the back. They make great gifts, and come read to wrap in a gift box with colorful tissue.
