Each Michigan shaped stained glass is approximately 8x10' and made from glass, copper foil and leading. with the Upper Penninsula sizes are approximately 11x13
When hanging your glass ONLY use commerical grade suction cups. trust me others just won't work. or a good ole hammer and nail above the window frame can work as well. Lordyhoardy is not liable for any breakage after shipping.
When caring for your glass the best practice is to buff it out with some wax for that gorgeous shine, however a light wipe down using warm water and soap works just fine
