This is a Christmas present I made for my boyfriend about a million years ago. He said he wanted a Ferrari in cross-stitch, and I was very much in love and thought it couldn't be very hard to do.
It wasn't that hard, but it took a really long time. It took a 16 hour train ride across Sweden (vertically), plus two days of my Christmas holiday to make it.
Plus some preparation. Basically I first of all found a nice Ferrari on the internet, made it very pixelated and reduced the colours in Photoshop, printed and then stitched it on the t-shirt. (With a mesh in between for counting stitches. Then you pull the mesh out thread by thread.)
He got just as happy as I hope for, except some complaining about the car not being centered properly onto the shirt. Which I just ignored.
It's still looking good, I really like it and I would certainly do it again.
(Do you know which Ferrari model it is? I didn't have a clue so I took one I liked, but luckily I choose the coolest one so he was really happy with that as well.)
