How great! I also love Jack! I'm going to make one up hopefully this weekend. I just have to go through my stash and find some black and white yarn. I know I have some here - somewhere - now where DID I put it?
"Creativity is not the finding of a thing, but the making something out of it after it is found."
I'm a chick with sticks and I'm not afraid to use them!
Here is the image I came up with. I uploaded it to the KnitPro link (see post above) and Yaay! I have a pattern. I plan to knit the scarf in black with Jack's mug in white on one end of the scarf. I think it will be fun!
I tried this before and it might work for you. Pixel art is just like a knit chart in my opinion. Find a pic of jack that you like... save the pic to your comp.... open the pic from where ever you saved it at and then zoom into it. You will see a bunch of squares that look just like a chart.
Here is another one I got a while ago. Just copy it (cuz there is no telling when I got it lol) and zoom into it. You will sorta see a chart. Maybe that'll help. Knit pro is great and all but I always want the outline of the object to be more crisp. Maybe you can put this and knit pros help together.
