I've already purchased 18 custom t-shirts from Maple this year. I loved them so much.
After one wash, the print faded to the point where all the details were gone. I was so happy, but I was also very disappointed.
Of course, it's probably a washing issue, but I've washed previous t-shirts in the same way, and while the image didn't fade to this degree, it's probably best not to use the washing machine.
If the print feels smooth and flat to the touch, it's probably best not to use it in the washing machine.
