Have had Zazzle complete a number of T-shirt projects in the past. This one had several design elements. It was well done. I will work with Zazzle again.

Basic T-Shirt, White, Large
I ordered about 20 shirts for a reunion. They arrived today on time but one the package was damaged. The shirts look great but the packaging was busted open and had been taped up. The shirts that were in the torn side were really dirty and I’m not sure it will wash out as it looks like greasy dirt. The printing looked great.
