Wow, I'm really impressed by all the elaborate blackwork borders that everyone is doing. I love the SNES border, Lileya! I actually had a somewhat similar idea, but my plan was to put a simple stripe of alternating light and dark purple circles below Super Mario Kart. I'm not sure yet if I want to frame the outside edges of the piece with anything.
Anyway, there's not that much more done since my last WIP photo, but this is all I'll be doing on the Super Mario Kart band until my next shopping trip for floss:
Man, I stink at photography.

The flash makes everything look a lot lighter and washed out than it does in person. I did use different colors to lighten up Yoshi a bit, but he's not quite THAT light in person. And the color on the tires definitely doesn't look that light and green normally. I probably could stitch some more with other substitutions, but I don't want to stitch the yellows and reds until I make sure the ones I buy will complement the others and have enough contrast.
