This shirt is a great personalized gift. The “Z” is made from hand dyed silk noil and sewn onto the shirt. I dyed the silk in several different tie-dye fashions using pennies, rubber bands, fiber reactive dyes, and water. You can order a shirt in a variety of colors with the letter of your choice. The gift receiver would definitely be getting a one-of-a-kind item! Here is where to find them in my etsy shop.
