I looked and looked but I can't find my camera :(
Thankfully, the spare phone has a 5MP built in so I just used that.
This is mellow yellow. If you click on the picture to see it big you'll probably get a better idea of my chopped off corner issues. This is how I did it.
Man, I should get a job in advertising. I could go around convincing people that any mistakes that are there were fully intended by the creator. Maybe I'll claim they were being ironic - since Alannis Morisette did that song, noone knows what it means any more so I think it's perfectly reasonable to claim my chopping off corners was an ironic take on traditional quilt blocks, when actually what happened was that I did my math while I was bored on checkout, and I didn't have an internet handy to tell me I was being a damn fool.
Also, I was convinced that a jelly roll was 7.5cm wide. Don't know where this number came from, but all my math features this number. Weird.
Anyway, I'm not sure whether to add 3cm to my length next time or just cut my diagonal from 1cm in on either side instead of the edge of the strip. I think I'll find out by making one block though, not a whole quilt.
