Here are his design sheets.


I photographed each chosen design - you can see this one has a red line drawn around it which is how I knew which ones he had chosen from his design sheets:

Then in Photoshop I cropped each picture right to the edge and erased all extra marks around the edges.

Most of his designs had been coloured in so I used the Hue / Saturation tool to select each colour group (red / yellow / green / cyan / blue / magenta) in turn and pull the lightness slider all the way to the right. This effectively bleached out all colour.

Then I converted to grayscale and increased brightness and contrast to get a nice, pure black and white image to trace.

As you saw above, each original image is tiny. I resized each chosen character to fit on a sheet of paper and printed them out.

I bought felt-tip fabric markers and tested them on the inside hem before starting.

I also ironed the duvet cover so that I had a nice smooth surface to work on.

Time to get started! I chose the first image to trace, put it on a piece of cardboard ...

... and slid it into the top left corner of the duvet cover.

Then I began tracing with the fabric marker.

First one done, only 119 to go! I'm not even kidding - that's how many images ended up on this queen-sized duvet cover.


This is after about four and half hours of tracing:


Preparing the images took around 2-3 hours (I didn't take note of the time) and the actual tracing took around 8 hours. I didn't do it all in one go but worked on it as and when I had time, packing it away in between tracing sessions.
And here is the final product, which I am so happy about - and thankfully Daniel likes it too!




I am so scared to wash it!! I promise I'll let you know if it fades, smears, streaks or in any other way doesn't come through the wash beautifully.
Update: I washed it and the drawings faded ever so slightly. I think it is due to the higher synthetic content of this inexpensive duvet cover - pure cotton or polycotton would probably have held the ink better. But it still looks good and even if they fade a lot more they will look more like pencil sketches, which is also good. Overall: success!
